This article addresses the common issue of “subscription link not updating”: in clients such as Clash, V2RayN, and sing-box, clicking Update Subscription does nothing, times out, fails to download, or leaves you with no nodes after the update. In many cases, the problem isn’t with the nodes themselves, but with your current IP, DNS resolution, browser, or system proxy settings.
1. First, check whether the subscription link is accessible
If an update fails, don’t keep clicking Update. First check whether the link still works. Copy the subscription link and paste it into your browser’s address bar. If a block of configuration text downloads, the link is probably working. If you see a 404 or 403 error, a blank page, or the page keeps loading, the link may have expired, access may be restricted, or your current network may be unable to connect.
If you’re using a free node subscription provided on this site, visit the relevant page and copy the latest link again to avoid using an outdated one. Don’t open the link directly from a chat app, as it may automatically escape characters and remove parameters from the URL.
2. Your IP environment can affect subscription updates
Some subscription services restrict access based on IP address—for example, if there are too many requests from the same IP, a data center IP is blocked, or your company or campus network restricts external access. In these cases, the client may report a “subscription update timeout” or “connection reset.”
- First, turn off your VPN or proxy and try updating over your local network.
- If that fails, switch to your phone’s hotspot to rule out an issue with your broadband provider.
- If you’re using public Wi-Fi, try a mobile network instead.
- Avoid refreshing the subscription repeatedly in quick succession; wait a few minutes before trying again.
Here’s a simple way to tell: If the same subscription link opens over mobile data but not on your home broadband, the issue is most likely your current network or IP environment.
3. DNS resolution issues can also prevent updates
Subscription links usually use a domain name, which the client must resolve first. DNS poisoning, a bad cache, or a resolution timeout can cause subscription updates to fail. Try temporarily switching to a common public DNS server in your system’s network settings, or flush the DNS cache on your router.
- Windows: Run “ipconfig /flushdns” to clear the DNS cache.
- macOS: Restart your network connection or switch Wi-Fi networks, then try again.
- Mobile devices: Turn on Airplane Mode for 10 seconds, then turn it off to reconnect.
Don’t run multiple proxy apps at the same time—DNS requests may be routed incorrectly, preventing the client from reaching the subscription URL.
4. Check browser and client proxy settings separately
Some users find that the subscription link opens in their browser but won’t update in Clash or V2RayN. This is usually because the browser uses the system proxy while the client doesn’t use a proxy for subscription updates, or vice versa. Check settings such as “Use proxy when updating subscriptions,” “Allow LAN,” and “System Proxy” in your client.
In Clash-based clients, try enabling the system proxy before updating the subscription. If that doesn’t work, turn it off and try updating with a direct connection. V2RayN users can right-click the subscription, select Update All Subscriptions, and check the logs for error messages. In sing-box GUI clients, check whether the configuration import page reports a format error.
5. Quick troubleshooting checklist
- Make sure the subscription link contains no extra spaces, line breaks, or non-English punctuation.
- Delete the old subscription and add it again instead of just clicking Update.
- Check that your system clock is correct; an incorrect time can cause HTTPS certificate errors.
- Temporarily disable your antivirus’s HTTPS scanning or network filtering, then try again.
- Check the client logs to determine whether the issue is a timeout, a DNS resolution failure, or an invalid configuration format.
The recommended troubleshooting order is: try another network, open the link in a browser, clear the DNS cache, add the subscription again, and check the logs. This is the quickest way to tell whether the problem is with the link, your IP, DNS, or the client environment. If the same subscription can’t be accessed from multiple devices and networks, the subscription source has probably expired and you’ll need a new subscription URL.
