If you want to get connected quickly, start with the Getting Started Guide and follow the shortest path through activation and import. This page is a system guide for ongoing reference: it explains not only which buttons to click, but also how subscriptions, clients, routes, rule modes, and system networking work together. If you cannot connect, speeds fluctuate, some apps bypass the proxy, or a configuration update fails, use the contents below to jump to the relevant stage.
This guide does not provide static installers or real subscription URLs. Get both the client and your personal subscription from the user panel; the example URL only illustrates field structure. For plans, follow the current options shown on the Plans page. To check coverage and route types, visit the Global Routes page.
Understanding Subscription Services and Backbone Routes
Separate your account, subscription, client, and route
A complete connection path consists of several independent parts. Your account lets you access the user panel, check plan status, and obtain configuration. A subscription is a route list and set of connection parameters generated by the panel. The client reads the subscription, establishes the encrypted connection, and takes over system traffic. The route determines which entry point carries traffic into the backbone network, which path it follows, and how it reaches the target region. Mixing these concepts makes troubleshooting misleading. For example, a client opening normally only proves that the program is installed; it does not mean the subscription is still valid. A successful subscription update does not mean the selected route suits the service you are accessing.
VPNBK covers 110+ countries / 150+ routes. Coverage indicates the range of regions and routes available, not that every connection should use the farthest or most complex route. In most cases, connection quality depends on the local access network, distance to the entry point, congestion across the border, the exit region, and the destination service. The practical approach is to choose the target region first, then compare stability among nearby routes instead of switching regions repeatedly. For regions, cities, and route types, use the Global Route List as your reference.
How to read route names
Route names usually include a region, city, or usage label. The region indicates the exit area, the city narrows the access location, and the usage label may suggest whether a route is better suited to general browsing, long-lived connections, streaming, or a particular network environment. Route types are engineering classifications of network paths, not a simple quality ranking. Dedicated or relay routes generally emphasize stable organization across the border, while direct routes depend more heavily on the actual path from the local carrier to the remote data center. Evening conditions, wireless interference, and changes in a home broadband exit can all make the same route perform differently in different environments.
Choose routes in a consistent order: first confirm the exit region required by the target service, then select a geographically nearby candidate. After connecting, check whether web pages, long-lived connections, or video match your intended use. Switch to another route in the same region only when problems persist. Change one variable at a time so you retain a useful basis for comparison. If you change the route, client mode, Wi-Fi network, and DNS settings together, even a temporary improvement will not reveal the real cause, and the next occurrence will send you back to trial and error.
The boundary between system proxy and tunnel mode
How the client takes over traffic determines which programs can use the connection. A system proxy normally routes browsers and apps that follow the system proxy settings. It is straightforward and suits ordinary web browsing and most desktop apps. Tunnel mode operates closer to the system network layer and can cover programs that ignore system proxy settings, but it depends more on system permissions, virtual network interfaces, and local security policies. If a browser works while a command-line tool or standalone app does not, the issue is often not the route itself but whether the application follows the current traffic-handling method.
Global mode sends all traffic the client can handle through the current route, making it useful for a short connection test. Rule mode decides between direct and proxied traffic based on domains, addresses, or usage scenarios, and is generally better for daily use. During troubleshooting, use global mode first to confirm the basic connection, then return to rule mode and check rule matches. Keeping global mode enabled permanently is unnecessary: local services, LAN devices, and sites that do not require international access are usually better served directly, reducing unnecessary routing and compatibility issues.
What to prepare before setup
Before starting, keep a browser window that can access the user panel and record your username. Your username and password are panel credentials and should be stored securely in a password manager. Do not post your personal subscription URL in public groups, screenshots, or support descriptions: the URL itself provides the route configuration associated with your account. When requesting support, describe only the platform, traffic-handling mode, route region, symptoms, and checks already completed; do not submit the full subscription content.
Also confirm that the device clock is set to automatic synchronization. Encrypted connections, certificate validation, and some login flows depend on accurate time. A clock offset may appear as a web certificate error, a failed subscription update, or a connection that drops immediately after being established. Then close other similar clients that modify system networking to prevent multiple programs from writing proxy settings or competing for a virtual network interface. Once these preparations are complete, move on to plan selection and account activation.
Choosing a Monthly Subscription or Data Package
Decide whether you need ongoing or metered use
VPNBK offers monthly subscriptions and data packages, which use different billing models. Monthly subscriptions suit continuous connections and relatively steady monthly usage; traffic resets monthly on the activation date. Data packages suit less frequent use and budgets based on actual consumption: they last until depleted and never expire. Before choosing, compare how traffic resets, not just the price. If your usage is spread out, unused monthly traffic still resets with the cycle. If you regularly browse, sync projects, or watch media, a continuing monthly subscription is usually easier to manage.
There are three monthly subscription tiers: ¥9.9/month includes 60GB, ¥18/month includes 250GB, and ¥28/month includes 500GB. Data packages are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB. Do not mechanically turn these capacities into a supposed “daily allowance,” because actual consumption varies with video quality, system updates, cloud sync, development dependency downloads, and background app activity. A better approach is to review a normal usage period in your existing network tool or system statistics, then choose the tier that covers your main workloads.
Choose by workload, not a single speed test
Web reading, text chats, and code requests usually involve frequent small transfers, so connection persistence and consistent response matter most. Video, system images, asset downloads, and cloud backups can consume traffic quickly. AI API calls and coding tools may not use much data per request, but interruptions to long-lived connections affect task continuity, so route stability often matters more than simply moving to a larger data tier. For more context, read VPN Picks for AI Coding Tools and Long-Connection Stability Tests and Comparing AI API Network Requirements.
If you cannot estimate usage accurately yet, choose based on your most common core tasks rather than counting every possible download. If you mainly browse, work with documents, and collaborate on development, start by observing actual consumption. If you clearly need continuous high-bitrate media or large downloads, choose a higher data tier. VPNBK supports unlimited devices, but that does not mean traffic is not shared across them. When computers, tablets, and other endpoints use the same account, include background sync and automatic updates in your estimate.
| Type | Options | Traffic rules | Best for |
|---|---|---|---|
| Monthly subscription | ¥9.9/month with 60GB · ¥18/month with 250GB · ¥28/month with 500GB | Resets monthly on the activation date | Continuous use with steady monthly workloads |
| Data package | ¥158/300GB · ¥358/1000GB · ¥658/3000GB | Lasts until depleted and never expires | Occasional use with spending based on consumption |
Upgrades, resets, and multi-device usage
When you upgrade a monthly subscription mid-cycle, the price difference is prorated into the remaining days. An upgrade is not simply an additional standalone data allowance, and you should not estimate the result as a full new cycle. Before proceeding, confirm the current plan, remaining status, and upgrade options in the panel; afterward, reopen the overview to check the update. Monthly traffic resets on the activation date, so each account’s reset point depends on its actual activation date rather than the calendar month.
Background tasks are the easiest thing to overlook when using multiple devices. Desktop systems may sync files, mobile apps may preload media, and development environments may download dependencies or container resources. When investigating traffic changes, pause obvious high-volume tasks first, then observe each device separately. Do not infer total consumption from the page state of a single foreground app. Unlimited devices removes the endpoint-count limit, but it does not change the plan’s capacity. In homes or multi-endpoint setups, assign clear roles—for example, use rule mode for everyday browsing and run large-file tasks only after checking the route and remaining balance.
Refund policy and pre-purchase checks
This service offers 14-day no-questions-asked refunds. Before purchasing, still verify the product type, traffic rules, and payment result so you do not confuse a monthly subscription with a data package that never expires. Payment methods are Alipay, WeChat Pay, and USDT. During checkout, rely on the order details and payment status shown in the user panel. Do not open multiple identical orders or submit repeatedly before the payment result returns.
After choosing a plan, keep a simple record of your intended use: primary platforms, common regions, whether long-lived connections are needed, and whether large-file tasks are involved. If speed or traffic issues arise later, this record helps distinguish an unsuitable capacity from an unsuitable route. Full pricing and product details are on the Plans page; the rest of this guide focuses on activation, delivery, and configuration.
Activation and ordering without an email address
Create your account and save your credentials
VPNBK does not require an email address; a username and password are enough to create an account. On the activation page in the user panel, choose a username that is easy for you to recognize without directly revealing your identity on other sites, then set a unique password. Do not reuse that password on common websites, since the account provides access to plan, order, and personal subscription details. Before submitting, check the input method, letter case, and leading or trailing spaces. Pay particular attention to password managers that may mistakenly save the page title as the username.
After creating the account, log out and sign in again once to confirm that the saved credentials work. This may seem unnecessary, but it can reveal a mistyped username, incorrect autofill, or a browser-saved error before payment. The login entry is the user panel, not the marketing page. From this guide, use First Month Free to open the activation flow; existing users can use the login link at the top. The language parameter and panel route will remain in the address after navigation, which is normal.
Verify the product and order in the panel
After signing in, open the plans area and confirm whether you are ordering a monthly subscription or a data package. A monthly subscription should show ¥9.9/month with 60GB, ¥18/month with 250GB, or ¥28/month with 500GB. A data package should show ¥158/300GB, ¥358/1000GB, or ¥658/3000GB. Create the order only after confirming that the name, price, and traffic rules match. Do not rely solely on browser history to return to an old checkout page; it may correspond to a previously selected product.
After creating the order, check its status first, then choose Alipay, WeChat Pay, or USDT to complete payment. Do not operate on the same order in multiple tabs at once. If the payment page is slow to return, go back to the order list and refresh the status instead of immediately creating another order. Duplicate orders do not necessarily mean duplicate charges, but they make reconciliation harder. When checking the payment, use the order number, product name, payment status, and plan status in the panel as your references. Never submit your password or full subscription URL when describing an issue.
The correct checks after payment
After payment completes and you return to the panel, check first whether the order has updated, then check the plan status in the account overview, and only then open the subscription area. If the order succeeded but the subscription is not visible on the old page, perform a normal refresh first. If the browser has strong page caching, sign out and back in. Do not reset the subscription repeatedly, pay again, or switch accounts at the same time; that turns a single status-refresh issue into multiple overlapping variables.
Monthly traffic resets on the activation date, and a mid-cycle upgrade prorates the difference into the remaining days. After upgrading, check the plan status again rather than relying on a page opened before the upgrade. Data packages last until depleted and never expire; after purchasing one, verify in the corresponding account section that it has been added. The client never handles payment for either product. It only reads the subscription delivered by the panel. Check order issues in the panel; investigate connection issues in the client.
Account security and subscription security are separate
Your username and password control panel access, while the subscription URL controls configuration access. Treat both as personal credentials. Store the password in a reliable password manager. Import the subscription URL only into your own clients; never paste it into an online parser or a public code repository. To move it between your own devices, use a controlled local method, then clear clipboard history and temporary text. VPNBK supports unlimited devices, so public sharing is unnecessary for importing your own devices.
If you suspect that the subscription URL has been exposed, use the available subscription-reset operation in the panel, then update every device you own with the new URL. After a reset, old configurations may stop updating, so check each device individually. Changing the account password is not the same as changing the subscription URL; resetting the subscription is not the same as changing the login password. Handle a security incident by checking account credentials and subscription credentials separately.
Common mistakes during activation
A common mistake is to look for an “account” in an app store or system settings immediately after payment. A marketing account does not automatically become a system network account. The actual delivery consists of the client entry point and subscription in the user panel. Another mistake is copying the panel URL from the browser address bar and assuming it is the subscription URL. The real subscription must be copied from the designated panel area or opened through the panel’s import action; a page URL cannot replace it.
Browser auto-translation, content-blocking extensions, or strict script policies can also affect checkout pages. If clicking a button does not produce the expected status, save the current order details, then sign in to the panel again in a normal browser window and verify them. Do not close the browser and repurchase from memory. Once these checks are complete, move on to obtaining the subscription and understanding how the client reads its configuration.
Get your subscription and understand the configuration
A subscription is not a single route file
Think of a subscription as a configuration entry point that the client reads periodically. It contains the routes available to the current account and the required parameters. Unlike manually adding a single connection, it lets the client obtain updated content when routes change, names are revised, or configuration is refreshed. Because it can retrieve account-specific configuration, a subscription must remain private. Forwarding it like an ordinary web link gives others access to an entry point intended only for your personal devices.
After signing in to the user panel, choose the client entry for your current platform in the download or subscription area, then copy the subscription or use the import action. Both the client and subscription are delivered through the panel; this page does not provide static installers. If the panel offers both copy and one-click import, one-click import is suitable when a compatible client is already installed on the current device. Copying is better when you need to paste manually inside the client. After importing, run an update yourself and confirm that the client has parsed the remote content into a route list.
Recognizing example URLs and real credentials
The URL below shows a common structure only. Its domain and token are clearly dummy values and cannot be used to connect. A real subscription must come from your own user panel. Do not construct a VPNBK URL based on the example, and do not assume that its field names appear in every client.
https://example.com/sub?token=YOUR_TOKENWhen copying a real subscription, avoid including leading or trailing spaces, line breaks, or non-ASCII punctuation. Some chat and note-taking apps convert long links to rich text, so a pasted URL may look complete even though its characters have changed. The safest process is to copy directly from the panel, paste immediately into the client’s subscription field, and clear the clipboard. If temporary storage is unavoidable, use a controlled local password manager rather than a publicly synchronized document.
What to watch during the first update
After adding a subscription, give it a recognizable local name, such as VPNBK, rather than a default name like “New Configuration.” Then run an update and check whether the client reports successful parsing and whether the route list appears. A successful update only means the client received the configuration; you still need to choose a route and enable traffic handling. If the update fails, first determine whether the subscription endpoint is unreachable, the text format is invalid, or the client does not support the current import method. Do not immediately blame a particular route.
If the client says the subscription is empty or the format cannot be recognized, confirm that the copy came from the panel’s subscription area, then delete the failed entry and add it again. Repeatedly editing a damaged entry can leave invisible characters behind. If one-click import opens the wrong app, return to the panel, use the copy method, and add it inside the intended client. When multiple similar clients are installed, the operating system may remember an earlier protocol association; that does not mean the subscription is invalid.
Updates, caching, and local changes
Clients generally keep a local copy of the last successful update, so an intermittent update failure may leave the old route list visible. Visible does not mean current. During troubleshooting, record the last successful update time and distinguish between “the update failed but the old configuration still connects” and “the configuration updated successfully but routes cannot connect.” The first points to panel status, the subscription URL, and the local network. The second points to route selection, traffic-handling mode, and system permissions.
Avoid directly editing core fields generated by the subscription. Manual changes may be overwritten during the next update or cause the configuration to diverge from the panel’s current content. For custom split tunneling, use the client’s override, rule-set, or local configuration layer so remote route data remains separate from local policy. This lets routes continue updating while preserving your rules. The advanced section below explains this layered approach further.
| Symptom | Check first | Next step |
|---|---|---|
| Cannot add subscription | Copy source, spaces and line breaks, client import entry | Delete the failed entry and copy it again |
| Update failed but old routes remain | Plan status, whether the subscription was reset, local network | Keep the old copy and test the update separately |
| Update succeeds but access fails | Route selection, system proxy, tunnel permissions | Switch to a route in the same region and verify traffic handling |
| Only some apps work | Whether the app follows the system proxy, rule matches | Check the traffic-handling method and split-tunneling policy |
Keep multi-device setups clear
Unlimited devices let the same account work across multiple endpoints you own, but management is still easier when every device has a clear name and follows the same update routine. Do not reset a subscription on one device and forget the others, and do not let multiple clients take over the same device at once. Keep one primary daily-use client per device; quit other tools and disable their startup launch after testing.
When one device fails while others work, the account, plan, and remote routes are usually available, so first check that device’s client configuration, permissions, and local network. If all devices fail to update at the same time, return to the panel and verify the plan and subscription status. Comparing devices can quickly narrow the scope, but use the same network and region where possible; otherwise the comparison introduces new variables.
Importing on Windows and macOS
Windows: Install, import, and take over traffic
On Windows, first obtain the VPNBK client from the download area of the user panel. After installation, confirm that no other tool is running that modifies proxy settings or virtual network interfaces. Open subscription management, choose Add Subscription, paste the URL copied from the panel, and save it. Run an update, select a route matching the target region, and enable the system proxy or the client’s traffic-handling feature. Do not adjust advanced parameters yet; first use a browser to verify basic connectivity.
If a normal browser works but some desktop programs cannot connect, check whether those programs read the Windows system proxy. Some use their own network settings, some command-line tools require explicit environment variables, and some are covered only in tunnel mode. Choose the method based on the application instead of repeatedly enabling both system proxy and tunnel mode. Before changing modes, disconnect and wait for the system network to recover, then enable the new method to reduce leftover settings.
Windows: Permissions and leftover proxy settings
Tunnel mode normally creates a virtual network interface and may trigger a system permission prompt. If permission is denied, the client may still display routes normally even though application traffic never enters the tunnel. Check the system network adapters and client logs to confirm that the interface was created successfully. If the device is managed by an organization, follow its network requirements instead of removing security components for a temporary connection.
After an abnormal client exit, the Windows system proxy may still point to a stopped local port, causing browsers to suddenly stop opening pages. Restart the client and disable traffic handling normally first. If the issue remains, open the system proxy settings and confirm that the manual proxy is off. This is leftover local state, not necessarily a broadband outage. Once recovered, reopen the client and check that it can write and remove the system settings correctly.
macOS: Network extensions and system authorization
On macOS, obtain the client from the user panel as well. The first time you enable the system proxy, you usually only need to allow the app to modify network settings. Tunnel mode may require confirmation of a network extension or VPN configuration. Follow the system prompt into Privacy & Security or Network settings, complete authorization, and return to the client to try again. Closing the prompt without authorizing can make a selected route appear active even though traffic is not actually being handled.
The import steps are similar to Windows: add the subscription, paste the URL, update routes, choose a region, and enable traffic handling. The menu bar status is useful for a quick check that the macOS client is running, but actual access and exit-region checks are still required. If it shows as started after boot but cannot connect, the client may have launched before the network was ready. Disable traffic handling, wait for the local network to stabilize, then update the subscription and reconnect.
macOS: App networking and Private Relay conflicts
Different macOS apps do not all follow system proxy settings in the same way. If the browser works but a terminal program does not, check whether the command-line program needs proxy environment variables or use a mode that can handle traffic at the system network layer. If macOS or the browser has another relay feature enabled, both paths may rewrite DNS and the exit region, causing changed region detection, verification loops, or intermittent connections. For troubleshooting, temporarily keep only one traffic path active; decide on a long-term combination after verification.
Do not immediately wipe the entire system network configuration to fix one app. First quit other networking tools and test the browser, then test the target app, and finally review the client logs. This order helps identify whether the issue is at the system or application layer. For a more detailed first-time macOS setup, read macOS Client Installation, System Permissions, and Subscription Import Guide.
| Check | Windows | macOS |
|---|---|---|
| Basic traffic handling | Check whether the system proxy is written and removed correctly | Check network-settings authorization and menu bar status |
| Tunnel mode | Confirm that the virtual network interface was created successfully | Confirm that the network extension or VPN configuration was approved |
| Some apps fail | Check the app’s independent proxy settings and command-line environment | Check the app’s traffic-handling method and other network relays |
| Network drops after exit | Check for a leftover manual proxy | Disable traffic handling and confirm the system network again |
Desktop verification baseline
After importing, choose a route with a clearly identified region, close other networking tools that could affect the test, and open an ordinary web page. Once it loads, check that the exit region matches the selected route. Then test the applications you actually need, such as development tools, media apps, or command-line requests. Do not rely only on the client’s “Connected” label: it usually means the local connection process has started or completed, not that end-to-end access works.
To verify network requests from the command line, request a trusted HTTPS site and inspect the response headers. The command below does not display a real subscription or change system settings. If the browser works but the command fails, return to the app proxy and traffic-handling settings instead of changing plans again.
curl -I https://example.comOnce the desktop setup is stable, enable launch at startup, automatic subscription updates, or automatic route selection. During initial setup, enabling only essential features reduces variables. The desktop setup is complete when connection, disconnection, and system-network recovery all work correctly.
Importing on iOS, Android, and Linux
iOS: Start the import flow from the panel
Get the iOS client entry from the user panel. After installing or opening the client, use the one-click import provided by the panel. If the system does not hand the link to the intended client, copy the subscription instead and paste it into the client’s subscription manager. On the first connection, iOS asks to add a VPN configuration; this system authorization is required for the client to handle device traffic. Approve it, return to the client, choose a route, and start the connection.
If the status bar shows a connection but the target app still cannot access the service, verify the basic connection in a browser first, then check whether the client is in rule mode or global mode. If only one app fails, it may have cached the previous connection or be using its own network path; fully quit and reopen it. Switching between Wi-Fi and cellular networks changes the underlying connection. If a long-lived connection does not recover, disconnect and reconnect in the client.
iOS: Subscription updates and background limits
Mobile operating systems manage apps based on battery level, background activity, and network status. When the client has not been opened for a long time, the subscription may not update automatically when you expect. Before extended use, open the client manually, confirm the plan status, update the subscription, and choose a route. If you see an old route list, do not delete every configuration immediately. Run an update and observe the result first; before deleting anything, confirm that you can still access the panel to obtain the subscription again.
When a device moves frequently between networks, the connection may retain an old network session. Disconnect first, wait for the current Wi-Fi or cellular connection to stabilize, and reconnect. If a public network requires a web-based login, temporarily disable the client, complete the network’s own sign-in page, and reconnect afterward. Otherwise, the login page may be routed through the rules and appear connected while every request returns nothing.
Android: System VPN permissions and battery policies
On Android, obtain the client from the user panel, paste the URL into subscription management, and update it. When starting the first connection, Android displays a VPN connection confirmation; approve it so the client can create a system tunnel. If the client reports startup failure, check whether permission was revoked and whether the system restricts the app’s background activity. Battery-management screens vary by device. The principle is to allow the client to maintain network service when needed, not to disable the system’s security mechanisms.
If the connection often drops after the screen locks, check battery optimization and background restrictions first. If the problem occurs only after switching between Wi-Fi and mobile data, prioritize rebuilding the tunnel. Avoid running multiple VPN-type apps at once on Android, because the system usually allows only one VPN configuration to handle the current network. Starting another app may invalidate the existing connection even if the original client does not immediately refresh its status.
Linux: Graphical clients and terminal environments
On Linux, obtain the client and subscription through the user panel as well. With a graphical client, the process remains the same: add the subscription, update routes, choose a region, and enable traffic handling. Remember that the desktop environment, application sandbox, and system services may manage proxy settings separately. A browser following the desktop proxy does not mean terminal commands inherit it automatically. Terminal programs may require explicit environment variables, while processes in containers have an independent network environment.
For a temporary command-line proxy test, set environment variables in the current terminal session. Use the port shown by the client’s actual local listener rather than copying an example from an online article. The command below only demonstrates the variable syntax; replace it with the local address supplied by the client before use. Temporary variables disappear when the terminal session ends, making this a useful way to determine whether a command-line tool fails because it does not read the system proxy.
export HTTPS_PROXY="http://127.0.0.1:LOCAL_PORT"
export HTTP_PROXY="http://127.0.0.1:LOCAL_PORT"
curl -I https://example.com
unset HTTPS_PROXY HTTP_PROXYDo not write proxy variables into global startup files for every shell unless you understand the scope. Global variables can quietly affect package managers, builds, internal services, and automated tasks. First test in a single terminal, confirm that the target program needs the variable, and then create local configuration for a specific project, script, or service. In containers, remember that a loopback address points to the container itself and may not reach the client listener on the host.
| Platform | Key authorization | Common boundary | Priority action |
|---|---|---|---|
| iOS | Allow adding a VPN configuration | Network switching and background updates | Stabilize the current network, then reconnect |
| Android | Allow the system VPN connection | Background restrictions and competition between apps | Check permissions and keep only one traffic path active |
| Linux | Allow the network interface required by the client | Separate desktop, terminal, and container environments | Confirm proxy variables and network scope layer by layer |
Use the same troubleshooting language across platforms
The interfaces differ by platform, but the troubleshooting layers are the same: Is the account valid? Did the subscription update? Is a route selected? Does the system allow traffic handling? Did the target app enter the current path? Describing these layers is more useful than saying only “the client does not work.” For example: “The subscription updated successfully, the browser works, but the terminal request does not use the system proxy.” That narrows the issue to the Linux terminal environment. Or: “Android updated successfully, but the connection did not recover after switching networks.” The focus should then be network switching and background state.
Completing setup on all five platforms does not mean every device must stay online permanently. Unlimited devices provide room for your endpoints; day-to-day management should still follow the principle of minimal complexity: disconnect unused devices, quit retired clients, and keep one primary traffic-handling tool per device. This prevents old configurations from interfering with the next subscription update or rule change.
Connection verification and troubleshooting
Build a repeatable verification process
Connection verification should not rely only on the client icon or a single speed test. Follow a fixed sequence: check whether the local network works with the client off; check whether the subscription updates; confirm that a specific route is selected; verify that traffic handling is enabled; open an HTTPS page in a browser; confirm that the exit region matches the route; and test whether the target app can complete a real task. Each step represents a different layer, and the failed step is where troubleshooting begins.
If the local network is already broken with the client off, restore it before switching routes. If the subscription cannot update but an old route still connects, focus on panel status and subscription credentials. If the update succeeds and a route is selected but no app can access anything, check system permissions, leftover proxy settings, and the tunnel interface. If only one service fails, examine its region requirements, rule match, DNS cache, and own service status.
Narrow the scope layer by layer when you cannot connect
Disable traffic handling first and confirm that direct network access returns, then reopen the client and select one geographically reasonable route. If it fails, switch to another route in the same region. Do not jump across several regions immediately, because that changes both the exit and the route. If all routes in the region fail, compare another traffic-handling method or local network. Change one variable at a time so you can tell whether the issue comes from the route, client, or access network.
Common client log messages can be understood by stage. Parse or update errors occur while obtaining the subscription. Connection timeouts occur between the local network and the entry point. Authentication or configuration errors usually relate to subscription status or local configuration. If the connection succeeds but the target service fails, continue by checking rules, DNS, the exit region, and app cache. If logs contain a subscription URL or sensitive fields, redact them before sharing; never publish the full block unchanged.
Slow speeds, instability, or dropped long-lived connections
First distinguish between a slow connection setup, a slow first page load, slow sustained transfer, and dropped long-lived connections. Slow setup may indicate entry-point reachability. A slow first page load can involve DNS or connection reuse. Sustained transfer is more affected by local bandwidth, congestion across the border, and remote-service limits. Dropped long-lived connections call for checks of wireless changes, device sleep, background restrictions, and route stability. Treating every symptom as “slow” removes the direction from troubleshooting.
During testing, pause large-file sync and system updates, then compare real tasks on the same device, network, and region among candidate routes. Do not open multiple speed-test pages at once; the tests consume bandwidth and alter later results. For Cursor, Copilot, streaming command-line output, or API calls, focus on whether the task completes continuously rather than on a momentary peak. See AI Coding Tool Long-Connection Stability Guide for related methods.
The browser works but an app does not
This usually means the route and basic network are working, while the difference lies in application traffic handling. A desktop app may ignore the system proxy, a command-line tool may need environment variables, and a mobile app may retain a session from before the connection was established. Fully quit the target app and reopen it while the client is connected. If it still fails, check the app’s own network settings or switch to a traffic-handling method that covers system traffic.
If the app accesses a LAN, development environment, or corporate intranet, global handling may send those addresses on an unnecessary route. Check that rules keep local ranges and internal domains direct. Do not send every local address through a remote route just to make one external service work; that can affect printers, storage devices, development servers, and authentication. A safer approach is to proxy only the targets that actually need it in rule mode.
Web verification loops, region mismatches, and DNS cache
Some websites consider the exit address, browser cache, account region, and DNS results together. Immediately after switching routes, an old session may continue using the previous connection, making the displayed region differ from the current route. Close the relevant tabs, let the old connection end, and reopen them. If needed, clear that site’s cache and session instead of wiping all browser data. If another secure DNS service or network relay is active, temporarily disable one of them for comparison.
For streaming, also confirm that the selected route matches the target content region. VPNBK’s route list labels regions and usage; use the Global Routes page as a reference. For media-app caching, region detection, and route switching, see the Streaming Access page. Avoid switching between several regions during playback, as the app may retain a mixed session and trigger more verification.
| Scope | Likely layer | How to check |
|---|---|---|
| Updates fail on every device | Plan, subscription, or current access network | Sign in to the panel to check status, then compare using another network |
| Only one device fails | Client, permissions, or local network | Compare with another device and check traffic handling on the affected device |
| Only one app fails | App proxy, rules, or cache | Restart the app and check the rule match |
| Issue begins after switching networks | Old session or tunnel not rebuilt | Disconnect, wait for the network to stabilize, then reconnect |
| Network drops after quitting the client | Leftover system proxy | Restart the client and disable traffic handling normally |
When to stop changing settings repeatedly
If the account status is normal, the subscription updates successfully, multiple routes in the same region fail, and the same behavior occurs on another local network, stop clearing and rebuilding the configuration. Keep the logs and reproduction steps, then submit the issue through the user panel’s support ticket entry. State the minimum reproduction path, such as “Update succeeds, a route in the same region is selected, and neither the browser nor the command line can establish an HTTPS request,” and note whether the issue reproduces on another device.
Repeated reinstalls delete local logs and working configurations, making diagnosis harder. Consider reinstalling only after confirming that client files are damaged, the configuration structure cannot be recovered, or system permissions are inconsistent. Before reinstalling, confirm that you can still sign in to the panel to obtain the client and subscription, then quit the old client normally and remove its system proxy. The goal of troubleshooting is not to reset everything, but to identify the layer where the failure occurs.
Daily maintenance, renewals, and advanced split tunneling
Establish a low-disruption maintenance routine
Stable use depends on predictable maintenance, not frequent configuration changes. In daily use, check the account plan status, whether the subscription updates normally, whether the primary route suits the current purpose, and whether the client can enable and remove system traffic handling correctly. When the route list changes, update the subscription first, then choose a suitable route in the same region. Without a clear problem, there is no need to change the mode, DNS, rules, and system network all at once.
Obtain client updates from the user panel rather than overwriting the existing program with files from an unknown source. Before updating, record the current subscription name, commonly used route region, and traffic-handling method. Afterward, verify a basic web page first, then your main apps. If the new version changes permission requirements, authorize it again as prompted instead of copying an old program directory. The client and subscription are separate update channels: client updates change program functionality, while subscription updates obtain route configuration. Do not confuse them.
Renewals, traffic resets, and upgrade management
Monthly traffic resets on the activation date, so use the account cycle shown in the panel rather than guessing by calendar month. When you want to continue using the service, verify the current plan and order in the panel before completing renewal. A mid-cycle upgrade prorates the difference into the remaining days; after upgrading, check the plan status and subscription update result again. Do not rely only on an old traffic figure in the client to determine whether an order completed, since the client cache and panel status may refresh at different times.
Data packages last until depleted and never expire, making them suitable for metered maintenance. After buying a new data package, check its credited status in the panel, then return to the client and update the subscription. With multiple devices, traffic changes reflect combined account usage, so inspect background tasks on each endpoint. If consumption is unexpectedly high over a short period, pause connections one device at a time, stop large-file sync and media preloading, and observe changes in the panel.
Design principles for rule mode
The goal of advanced split tunneling is not to pile up rules, but to send traffic along the shortest explainable path for its purpose. LAN addresses, local services, and sites that do not require international access usually stay direct. Services that need a specific exit region follow the corresponding policy. Uncertain traffic can use the default policy. Start with broad, stable categories and add exceptions only when a clear misclassification appears. Large numbers of duplicate or overlapping rules make results unpredictable.
Rules are usually matched in order, so specific exceptions should come before broad rules. For example, if a development domain needs a particular region while similar sites use the default route, put the specific domain first and the general category afterward. After editing, use the target app to verify the match and keep a rollback option. Do not directly modify the remote configuration generated by the subscription. Prefer the client’s override layer, local rules, or policy groups so route updates remain independent from personal rules.
# The following only illustrates split-tunneling structure; it is not a complete importable configuration
rules:
- DOMAIN,internal.example,DIRECT
- DOMAIN-SUFFIX,example.com,PROXY
- MATCH,PROXYThe domains in the example are reserved demonstration values. PROXY and DIRECT express policy meanings only. Field names and configuration structures differ between clients, so follow the current client interface and documentation. Before importing a large rule set from an unknown source, understand which domains and addresses it will handle. More rules do not automatically mean more accurate decisions; outdated entries may send normal services to the wrong region.
Splitting policies for AI tools, media, and development environments
AI tools commonly use long-lived connections, streaming responses, and API requests, so the priority is a stable exit and continuous connectivity. Media apps care more about region matching and sustained transfer. Development environments may access public dependencies, private repositories, container networks, and local services at the same time. Binding every use case to one global policy means every switch affects every task. A better approach is to create policy groups by purpose and keep candidate routes within the same region.
When using Cursor, Copilot, or command-line AI tools, avoid switching routes repeatedly during a task. For API calls, distinguish application timeouts, server-side limits, and network interruptions instead of attributing every error to the route. See Practical Comparison of Fixed Egress, Concurrency, and Timeout Issues for AI APIs for more analysis. For media apps, restart the app session after changing regions to reduce interference from old cache.
In a development environment, the terminal, editor, container, and browser may each use a different network path. Start by drawing a simple data flow: which process makes the request, whether it reads the system proxy, whether it runs in a container, and whether the target is public or local. Set environment variables or rules only after the path is clear. Global proxy variables may be convenient, but they can create hidden failures in package managers, internal repositories, and automated tasks.
What to back up and migrate
When moving to a new device, you do not need to back up all node content generated by the subscription; obtain it again from the panel on the new device. More useful items to preserve are custom rules, policy-group names, frequently used regions, and troubleshooting records. If a backup contains the subscription URL, encrypt it. Before sending configuration snippets to anyone else, remove the subscription, username, token, local paths, and other personal information.
Before retiring an old device, disable client traffic handling normally and confirm that system networking has recovered, then delete local subscription and client data. After importing on the new device, follow this guide’s verification process for the browser, target apps, and recovery after disconnecting. Do not reset the subscription, upgrade the plan, and rewrite every rule on the same migration day; if something fails, it will be difficult to identify the step responsible.
Build a reusable operating baseline
After completing the full process, you should have a concise baseline: you can sign in to the user panel; know whether the plan is a monthly subscription or data package; know where to obtain the client and subscription; can update configuration on the devices you actually use across the five platforms; have clear choices for common regions; can connect and remove traffic handling normally; have verified your main apps; and keep custom rules separate from the remote subscription. The clearer the baseline, the less future maintenance depends on trial and error.
When an issue returns, compare changes against the baseline: Did you change the local network, update the client, reset the subscription, add a rule, or switch the exit region? Once you identify the most recent change, roll it back or test it separately instead of reinstalling everything. For human support, open the User Panel Support Ticket and submit the platform, route region, traffic-handling method, symptoms, and reproduction steps.
