This article addresses the problem of subscription links not updating when multiple team members use clients such as Clash, V2RayN, and sing-box. It covers common causes—including the link itself, network conditions, account security controls, client cache, and inconsistent member practices—and provides troubleshooting steps you can follow right away.
1. First determine whether the issue affects one person or the whole team
In a team setting, don’t start by repeatedly refreshing the subscription. First, ask two or three members to test the same link on different networks. If no one can update it, the subscription URL may have expired, the server may be returning an error, or access may be restricted. If only a few members are affected, the cause is usually their local proxy status, DNS, client cache, system time, or account environment.
- Copy the subscription link and open it in a browser to see whether it displays node information or downloads a file.
- Turn off the current proxy and try updating again, to avoid a loop caused by using an old node to update a new subscription.
- Test on a mobile hotspot, company network, and home broadband to check whether the issue is related to the network’s public IP address.
- Ask members to note the error message, such as timeout, 403, 404, TLS error, or empty response.
2. Why account environment stability can affect subscription updates
Many subscription systems impose restrictions based on login status, request frequency, IP changes, User-Agent, or the number of devices. If a team shares one account or subscription and many members update it frequently within a short period, this may trigger security controls. The result can be a failed subscription fetch, empty content, or an authorization error. This is especially likely when multiple people in the office share a public IP address while members in other locations refresh at the same time.
We recommend that teams establish consistent rules: don’t post subscription links in public places beyond the team announcement channel; don’t configure scripts to update every minute; and change the link promptly when a team member leaves. For the free node subscriptions provided on this site, follow the instructions on the page to avoid temporary unavailability caused by excessive requests.
3. Troubleshoot each client
- Clash Verge / Clash Meta: Go to “Subscriptions/Profiles” and try a manual update first. If it fails, delete the old profile and re-import the subscription URL, then check whether the system proxy is enabled.
- V2RayN: Right-click the subscription group and select Update Subscription. If nothing changes, try “Clear System Proxy” and “Check for Subscription Content Updates,” then restart the client.
- sing-box: Make sure there are no extra spaces in the configuration source URL. If you use a third-party panel to convert the subscription, first check whether the original subscription works.
If the subscription opens in a browser but won’t update in the client, check whether the client is being blocked by the firewall, certificate verification is failing, the proxy mode is incorrect, or the client version is outdated. Team administrators can provide a standard client version and screenshots of the import process to prevent issues caused by members changing settings on their own.
4. Recommended troubleshooting process for teams
- The administrator should verify that the subscription link works before anyone else tests it. Don’t have all members refresh at the same time.
- Use a clean device with no proxy enabled to test the update.
- If you see a 403 or authorization error, stop making repeated requests and check the account login, device limit, and whether the link has been exposed.
- If you see a timeout, switch networks or DNS, then test the link in a browser again.
- Once the link is confirmed to work, notify all members to update and specify how often they should do so.
Finally, remember that a failed subscription update doesn’t necessarily mean the nodes are down. Often, the cause is an unstable account environment, inconsistent access practices across the team, or client cache. Keeping a designated administrator, a consistent update schedule, and a standard client version can significantly reduce subscription issues when team members use proxy services.
