What Is a Subscription Link? A Beginner’s Complete Guide to Getting, Importing & Updating
Learn what subscription links do, where to copy one, how to import it, how updates work, and what to do if a link is exposed.
What Is a Subscription Link, and How Is It Different from a Plan?
A subscription link is a dedicated address that lets a client retrieve connection configurations. It usually contains account-related access credentials. After importing it, the client uses the address to get the server, port, protocol, and other connection details, instead of requiring you to enter each item manually.
The word “subscription” can be confused with a recurring payment. A plan determines the traffic and usage terms available to an account; a subscription link delivers configuration details. Copying an address does not activate a plan, and a successful import does not guarantee that the account has available traffic. Traffic packages may also provide access to routes through a subscription link; check the entry point in the service panel.
| Term | What it does | What to know |
|---|---|---|
| Plan | Defines billing, traffic allowance, and other account benefits | Updating a subscription does not increase the plan allowance |
| Subscription link | Lets a client request a route list or configuration file | May contain access credentials and should be kept private |
| Single-node link | Shares the connection details for one route | It is not the same as a complete subscription that can be updated over time |
| Configuration file | Stores nodes and may also contain proxy groups, rules, and DNS settings | Its contents depend on the export format and client support |
A QR code is simply another way to carry information. It may contain a subscription address or a single-node link. After scanning it, check the type identified by the client rather than relying on the QR code’s appearance. A static copy imported from a file may not retain the original online update address.
Where to Get a Link and What to Check Before Copying
Start by signing in to the service’s official website, then look for subscription management, usage instructions, or a client import entry. Labels vary between interfaces. The key is to copy the subscription address intended for a client—not the browser address for an account, plan, or login page.
VPNKG requires no email address; an account can be opened with a username and password. Existing users can go to the user panel login. Client downloads are available from the panel download page. Follow the panel’s instructions for supported import methods and configuration formats instead of guessing based on the client’s name.
- ✅ Confirm that the page belongs to the service you use and that the account is in good standing.
- ✅ Prefer the panel’s copy button to avoid missing the end of a long address.
- ✅ Check that the target client matches the export format. Do not include quotation marks or explanatory text when copying.
- ❌ Do not post the full link in public comments, group chats, or shared documents to ask for help.
Import into a Client: Match the Format Before Connecting
Client interfaces differ across Windows, macOS, iOS, Android, and Linux, but the basic process is similar. Desktop clients commonly let you paste an address or import a configuration file. Mobile clients may support scanning a QR code or opening a link in an app, while Linux may require a configuration file and command-line steps. Do not assume menu names are the same across platforms.
Also distinguish protocol support from subscription-format support. Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different proxy protocols. A client that can parse a subscription format may not have a connection core that supports every protocol in it. Conversely, support for a protocol does not mean the client can recognize every configuration file. This explains general concepts and does not mean VPNKG offers all of these protocols.
- Install a compatible client. Get it from the panel download page or an official source it recommends, and check the operating system and client requirements.
- Add a remote subscription. Find the subscription, configuration, or remote configuration option and paste the complete address. If one-click import is available, first confirm that it opens the intended app.
- Fetch or update the configuration. Wait for the client to retrieve it and check that a route list appears. If it fails, read the error first instead of immediately switching connection modes repeatedly.
- Activate the imported configuration. Some clients let you save multiple configurations; adding one does not automatically switch to it. You may also need to select a route or proxy group.
- Enable the proxy and verify it. Grant the system network permissions required by the client, then test an app you actually use. A page loading does not mean every app is using the same connection.
Using the system proxy and routing traffic through a virtual network interface are different approaches. Some apps do not follow the system proxy, while some use cases need broader traffic routing supported by the client. Follow the client’s instructions first. Do not enable multiple proxy tools just to make an icon show “Connected,” as their settings may conflict.
How Often Does It Update Automatically, and Does It Reset Traffic?
There is no single update interval that applies to every client. Automatic updates depend on app settings, any interval suggested by the subscription, and the operating system’s background activity rules. Some apps fetch updates at startup; others let you schedule them. Mobile system restrictions may delay scheduled updates. Check the last successful update time and its result to see whether an update worked.
You can update manually if the service announces route changes, the list looks outdated, or connections keep failing. After a successful update, check whether the selected route is still available and choose another if needed. Do not assume that clicking “Update” means the client received new configuration; it may keep using a local cache after a failed request.
Updating a subscription does not recalculate plan traffic. VPNKG monthly subscription traffic resets on the activation date, and the price difference for a mid-cycle upgrade is converted into remaining days. Traffic packages remain available until used and do not expire. These are account rules, separate from refreshing a local configuration.
Import Failures or a Connection That Won’t Load: How to Troubleshoot
First identify where the problem occurs: the address cannot be fetched, the configuration cannot be parsed, or a route is available but cannot reach the destination. Each stage calls for a different fix. The subscription server and the proxy server are not the same thing, so a failed fetch does not necessarily mean that every route is unavailable.
- Address reported as invalid: Copy it again from the panel and check for spaces, line breaks, or an account page mistakenly copied as a subscription link.
- Insufficient permission or expired link: Check the account status and whether the subscription was reset. After an old address expires, import the new one.
- Response cannot be parsed: Check the subscription format and client version. A login or error page returned in place of the configuration may also appear as a parsing failure.
- Routes appear but connections fail: Check that the selected configuration is active, that system network permissions are granted, and that no other proxy app is interfering.
- Only some apps have problems: Check whether they follow the system proxy or are set to connect directly by split-routing rules, then check the DNS resolution path.
A DNS leak occurs when domain lookups use an unexpected resolution path and may expose query information. A changed exit address alone does not prove that no leak exists. Check the client’s DNS mode, system settings, and the browser’s own encrypted DNS. Do not copy unknown configurations without review or treat a single test result as a privacy guarantee for every app.
Updating a subscription will not turn a direct route into a relay or an IEPL dedicated line. Route architecture, supported protocols, and local rules are separate considerations. Diagnose problems using the current configuration and the behavior of the affected app. If the issue persists, use a panel support ticket to share redacted error text and system and client details. Do not attach subscription credentials.
After a Link Is Exposed: How to Reset and Verify It
Deleting a public post can limit further sharing, but it cannot retrieve a link someone has already copied. Look in the account panel for an option to reset the subscription, regenerate credentials, or perform a similar action. If there is no clear option, ask support through a ticket. Changing the account password and revoking subscription credentials may be separate actions; do not assume that the former invalidates the old link.
- Revoke the old credentials. Follow the panel instructions and confirm that the reset applies to subscription access, not just a display name.
- Replace the old address on every device. Include computers and mobile devices you rarely use, as well as sync tools that store configurations.
- Fetch and activate the configuration again. Confirm that the new address updates successfully, then remove old subscriptions and exported files you no longer need.
- Confirm what was revoked. Use the panel instructions or a support ticket to check that the old address is revoked and whether previously issued node credentials were rotated as well.
An old link no longer retrieving configuration does not necessarily mean that node details already downloaded have immediately become invalid. That depends on how the service rotates credentials. Do not submit a subscription address to an unfamiliar online conversion site. Conversion may require access to the full configuration, so use a compatible format provided by the service or a trusted local method instead.
