This article addresses the problem of what to do if a subscription link won’t update when multiple team members use clients such as Clash, V2RayN, and sing-box: why some people can update while others fail, and how it relates to the account, network environment, and client cache.
1. First determine whether the issue is a “broken link” or a “local update failure”
When your team uses the same subscription, don’t start by repeatedly deleting and reinstalling everything. It’s best to first test on two devices using different networks—for example, one on the company Wi-Fi and one on a mobile hotspot. If all of them fail, the subscription URL may have expired, permissions may have been revoked, or the server may be temporarily unavailable. If only some members fail, it is most likely a local environment, DNS, proxy mode, or cache issue.
- Copy the subscription link and make sure there are no extra spaces, line breaks, or Chinese punctuation marks.
- Open the link in a browser and check whether it downloads a block of configuration text.
- Switch to a mobile hotspot to rule out company network blocking or DNS pollution.
- Ask other team members to update using the same link and compare whether it is a device-specific problem.
2. The most common causes in a team environment
When multiple people share the same subscription, update failures are often related to account environment stability. For example, frequently pulling the subscription from different regions, devices, and clients at the same time may trigger risk controls or temporary restrictions. A company network may also block certain subscription domains, causing the client to show errors such as timeout, failed, or network error.
- Client cache issues: the old subscription file is corrupted, preventing new content from overwriting it.
- Incorrect system time: certificate validation fails, so the HTTPS subscription cannot be accessed.
- Proxy mode conflict: after enabling global proxy, the client tries to update the subscription through an unavailable node.
- Subscription URL permission changes: the administrator changed the link or the old link was disabled.
- DNS resolution issues: the same link resolves differently under different networks.
3. Check in this order for maximum efficiency
Using graphical clients such as Clash Verge, V2RayN, and sing-box as examples, it is recommended to troubleshoot in the following order. First, turn off the current proxy or switch to “Direct” before updating the subscription; if you must access the subscription through a proxy, switch to a verified working node and try again. Second, delete the old subscription configuration and add the link again instead of only clicking refresh. Third, clear the client cache or restart the client, and if necessary restart the computer or phone.
If it still fails, copy the subscription link into a browser for testing. If it opens, that means the link itself is accessible and the problem is most likely with the client; if it does not open, switch networks, change DNS, or contact the subscription provider to confirm the link status. The free nodes provided by this site may also become temporarily unavailable due to network fluctuations or maintenance, so it is recommended to keep multiple backup subscription sources to avoid having the whole team rely on a single link.
4. Stability recommendations for team use
Teams should not casually forward the same subscription link to too many devices, nor should they enable high-frequency automatic refreshing across scripts, routers, phones, and computers. It is recommended to assign one administrator to maintain the subscription sources and notify everyone of the update schedule in a unified manner; members should refresh manually only when needed. If the client supports an “update interval,” set it to a longer duration to avoid a large number of requests in a short period of time.
In addition, team members should record their client name, system version, error screenshot, and current network. During troubleshooting, collect the information first, then determine whether the issue is related to account permissions, the subscription URL, the network environment, or the client. Handling what to do if a subscription link won’t update this way is faster and more reliable than blindly switching software.
