A VPN subscription link is the address a client uses to retrieve server configurations. It is not usually a website to open directly in a browser, nor is it a single server itself. When the client requests the address, it receives server names, host addresses, ports, protocol settings, and group information, then organizes them into a selectable server list.
For beginners, the three concepts most easily confused are a subscription link, a single-server configuration, and a client. The client makes the connection; a single-server configuration describes one route; and a subscription link delivers a set of configurations to the client and provides an update path when the server-side content changes. Once these are clear, importing, updating, and troubleshooting become much more straightforward.
What’s inside a subscription link
There is no single subscription format. Some services return an encoded server list, with entries that may use Shadowsocks, VMess, Trojan, VLESS, Hysteria2, or TUIC. Others return structured settings for a specific client, such as a configuration file containing proxy groups, rules, and DNS settings. Importability depends not only on whether the link works, but also on whether the client understands the returned format and protocols.
A protocol name does not indicate route quality. Protocols define how the client and server establish, authenticate, and transport a connection; direct, relayed, and IEPL routes describe the network path the traffic takes. A direct route connects to the remote entry point through the local network; a relay passes through an intermediate server first; and an IEPL route uses a designated cross-border network path. Real-world performance still depends on the local carrier, time of day, routing, and destination, so protocol names alone are not enough to judge it.
| Item | Primary role | Common misconception | What to do when it changes |
|---|---|---|---|
| Subscription link | Delivers a complete set of servers and settings to the client | Treating the link like a regular bookmarked webpage | Update it in the client; reset it from the dashboard if the credentials are exposed |
| Single-server configuration | Describes the connection parameters for one server | Assuming other servers will appear automatically after import | Import the new configuration again, or switch to subscription management |
| Client | Parses settings and handles connections and traffic routing | Assuming every client supports every format | Choose a version compatible with the subscription format and protocols |
| Route path | Determines whether traffic uses a direct, relay, or dedicated entry point | Confusing route types with protocol names | Refresh the list, then choose a route suited to the current network |
Get it from the dashboard and store it safely
The correct source is the subscription section of the service dashboard. After signing in to the 6KVPN dashboard, confirm your current plan and traffic status, then open the client or subscription page and copy the link for your platform. If the dashboard offers both a general subscription and client-specific formats, choose the format your client explicitly supports instead of copying the longest-looking option.
After copying it, do not paste it into a browser address bar as a test. The browser may display text, trigger a download, or show an error because it cannot render the format; none of these results reliably indicates whether the client can import it. A safer approach is to return to the client and paste it under “Add subscription,” “Import from URL,” or a similarly named option.
- Verify the source: copy only from the signed-in service dashboard. Do not use links from chat history, OCR from screenshots, or links forwarded by someone else.
- Verify the format: check the dashboard guidance for Windows, macOS, Android, iOS, or Linux and choose the matching subscription type.
- Copy it in full: make sure the beginning, ending, and all parameters are intact, with no extra spaces or line breaks.
- Import directly: open the client’s subscription manager, paste the URL, and save it.
- Run an update: refresh once after saving and confirm that the server names appear.
- Verify completion: connect to a server, then check whether the exit IP and DNS requests match your expectations.
How to import on the five major platforms
Button labels vary by platform, but the workflow is the same: install a compatible client, open subscription management, add the URL, update the list, and select a server. Do not confuse the system’s traditional VPN settings with a proxy subscription client. The VPN page in system settings is generally intended for connection types supported natively by the operating system and may not parse a subscription containing multiple proxy protocols.
| Platform | Common import location | What to check after import | Platform-specific detail |
|---|---|---|---|
| Windows | URL import in the Config, Subscription, or Profiles section | System proxy mode, virtual network adapter mode, and traffic-routing rules | Whether system proxy settings are restored after the client exits |
| macOS | Subscription management inside the menu-bar client | Network extension permissions, system proxy, and the active configuration | System approval is required the first time the network extension is enabled |
| Android | URL import from the sidebar menu or configuration page | System VPN permission, background operation, and battery settings | Power-saving settings may stop the client in the background |
| iOS | The client’s subscription, configuration, or remote-file section | System VPN configuration permission and on-demand connection settings | Client capabilities are constrained by the system’s network-extension framework |
| Linux | Subscription pages in graphical clients or configuration management from the command line | Desktop proxy, TUN mode, permissions, and DNS | System proxy takeover works differently across desktop environments |
Windows and macOS
Desktop clients usually offer both system proxy and virtual network adapter modes. System proxy mode mainly affects apps that follow the operating system’s proxy settings; virtual adapter mode generally covers more traffic but is also more susceptible to firewalls, permissions, and other networking software. Beginners should start with the client’s default mode to verify the connection, then adjust it as needed.
The first time you enable the relevant features on macOS, the system may ask you to approve a network extension or VPN configuration. Even if the subscription imported successfully, traffic may not enter the client after approval is denied. Check the relevant permission in System Settings instead of repeatedly deleting the subscription.
Android and iOS
Mobile platforms display a system-level VPN permission the first time you connect. This permission lets the client create a local network tunnel; it does not change the subscription link. On Android, also check background restrictions: if the system stops the client after the screen locks, the connection may appear to drop unexpectedly. On iOS, confirm that the selected app supports the format and protocols returned by the subscription.
Linux
Linux differs mainly because of the distribution, desktop environment, and execution method. Graphical clients follow a workflow similar to other desktop platforms; command-line cores may require converting the remote subscription into a supported configuration before loading it into a service process. Read the client’s own documentation before importing, and do not give one client’s configuration file directly to another core.
- ✅ The client recognizes the subscription format and supports the protocols actually used in the list.
- ✅ After updating, server names appear instead of an empty configuration.
- ✅ The system has granted the network-extension or VPN-configuration permission when connecting.
- ✅ The exit IP changes as expected after switching servers.
- ✅ DNS queries follow the expected path rather than continuing through an unsuitable local resolver chain.
- ❌ Assuming every app is using the proxy just because the client says “Import successful.”
- ❌ Running multiple clients that take over the system proxy or virtual network adapter at the same time.
How often should you update a subscription?
“Update subscription” and “change subscription link” are different actions. In most cases, the original link continues to retrieve the latest server-side configuration as long as its credentials have not been reset. When server names, entry parameters, or groups change, the client must request the subscription again to see those changes. An unchanged-looking link does not mean its returned content is unchanged.
There is no fixed update interval that applies to every client. Some update only when you click a button, some support automatic refreshes, and some request remote settings at startup. The exact behavior depends on the client and its current settings. Instead of memorizing an interval, update it proactively after the first import, when the dashboard reports route changes, when the list has not changed for a long time, when an older server repeatedly fails, or after resetting the subscription credentials on another device.
Save your current selection before updating, then check the default group afterward. Some configurations may have their server names or group structure changed by the service, causing the client to return to automatic selection or another default. If the connection behaves differently after the update, first check the selected server and mode before treating it as a network failure.
How to verify that an imported subscription is working
A successful subscription import only means the client parsed the configuration. Full verification also covers the connection, traffic capture, exit address, and DNS path. First close other tools that may take over networking, connect to a server, then open this site’s IP Lookup page to check the exit details. Disconnect and run the lookup again to see whether the result returns to the local network.
If the browser’s exit location has changed but an app still uses the original network, the issue is usually the proxy coverage or traffic-routing rules. System proxy mode affects only software that follows proxy settings; some games, command-line programs, and apps with their own network stack may not follow automatically. Check whether the client offers virtual network adapter mode, or add an explicit rule for the target app.
Traffic-routing rules determine which requests use the proxy and which stay direct. They may match domains, IPs, apps, or rule sets. Rule order matters: an earlier match may take effect before a later general rule. If a target site takes an unexpected path, inspect the match result in the connection log instead of repeatedly switching servers.
A DNS leak occurs when domain lookups bypass the expected resolver path, exposing the local resolution environment or producing results that do not match the route’s exit location. Check the client’s DNS settings, the system’s encrypted DNS, the browser’s secure DNS, and virtual network adapter mode together. When multiple layers specify their own resolvers, the final request path may differ from what the client interface displays.
- Temporarily quit other programs that modify the system proxy, VPN settings, or routing table.
- Update the subscription and choose a clearly identified server instead of relying on an ambiguous automatic group.
- Look up the exit IP after connecting and confirm that its country or region matches the selected route.
- Check the DNS resolution path to rule out the system or browser bypassing the client’s settings.
- Test the browser and the target app separately to confirm that the routing rules cover the actual use case.
- Check the network again after disconnecting so leftover system proxy settings do not affect normal access.
Common errors and a troubleshooting order
Subscription invalid or parsing failed
First return to the dashboard and copy the link again, ruling out truncation, spaces, and old credentials. Then confirm that the client is set to import from a URL rather than a local file. If the link responds but still cannot be parsed, the returned format is usually incompatible with the client, or the client version does not support one of the listed protocols. Choose the matching format provided by the dashboard or use a compatible client.
The server list appears, but every connection fails
This is no longer simply a subscription-parsing issue. Check the system clock, network permissions, firewall, virtual adapter driver, and whether the current network can reach the entry point. Then update the subscription and try different route types. Do not change the protocol, DNS, routing rules, and system proxy at the same time, or it will be difficult to tell what restored the connection.
The server list did not change after updating
The client may be reading a cache, or you may have updated a different configuration. Confirm that the active configuration name matches the subscription you just updated, and check whether the client offers a forced refresh or cache-clearing option. If the dashboard has reset the subscription, failure to update the old link is expected; import the new link again.
Some websites do not open after connecting
Check routing matches and DNS first rather than assuming the server is unavailable. The target domain may have been assigned to a direct route, or DNS may return results that do not match the exit region. Switch to the client’s default rules for comparison, then restore custom rules one at a time; this is usually easier than reinstalling the client.
- ✅ First verify the link source, completeness, and credential status.
- ✅ Then verify compatibility between the subscription format and the client protocols.
- ✅ After importing, check system permissions, proxy mode, and virtual adapter status.
- ✅ Troubleshoot DNS and routing details only after a connection works.
- ❌ Do not run multiple network-control tools at the same time during troubleshooting.
- ❌ Do not paste the complete subscription link into a public forum or public screenshot.
How to reset an exposed link
Once a subscription link appears on a public page, shared document, public repository, or device you cannot control, treat its credentials as exposed. Deleting the public content only limits further sharing; it does not invalidate copies of the old link. The correct response is to reset the subscription in the service dashboard, then import the new link into your own clients.
After a reset, the old link should stop retrieving valid settings, and clients using it will no longer be able to update. Replace the link on your other devices one by one. Simply deleting a server from the client without resetting the dashboard credentials still leaves anyone with the old link able to retrieve the configuration.
After resetting, check everywhere the link may have appeared, including browser sync history, clipboard sync, automatically backed-up configuration files, command history, and public screenshots. If configuration files must be transferred between devices, use controlled private storage; do not put the subscription URL in a public script or repository for convenience.
