This article addresses the common issue “What should I do if my subscription link won’t update?” If updating a subscription in clients such as Clash, V2RayN, or sing-box fails, times out, shows a blank page, or doesn’t retrieve any nodes, follow these steps to check your network IP, DNS, browser environment, and client settings.
First, check whether the subscription link itself works
When an update fails, don’t immediately reinstall the client. First, check whether the link is still accessible. Copy the subscription link into your browser’s address bar and open it. If a download starts or you see a long string of configuration text, the link is usually working. If you see a 404 error, a permission error, or a blank page, the link may have expired, been copied incorrectly, or need to be refreshed.
- Make sure the link starts with http/https and has no extra spaces at the end.
- Check that you haven’t confused the subscription page address with the subscription link.
- If you’re using this site’s free nodes, copy the subscription address from the latest page.
Note: Some subscription links appear as garbled text or a long string in the browser. This is normal and doesn’t mean the link can’t be imported.
How your IP environment can affect updates: your network may be blocking subscription requests
Many users find that their nodes still work, but their subscriptions won’t update. This is because the client sends update requests over your current direct connection, not through the proxy. If your home broadband, campus network, workplace network, or public Wi-Fi blocks the subscription domain, the request may time out or fail to connect.
- Switch to your phone’s hotspot, then click “Update subscription” in the client.
- If the update works over the hotspot, your original network may be restricting access.
- Try enabling “Use proxy when updating subscriptions” or a similar option in the client.
- If you already have a working node, connect to it before refreshing the subscription.
Key point: A failed subscription update doesn’t necessarily mean the node is broken. Your current IP environment may simply be blocking access to the subscription file.
DNS issues: resolution failures can leave the client spinning
If the client reports “lookup failed,” “DNS error,” or that it can’t resolve the hostname, the problem is usually related to DNS. You can temporarily change your system DNS to a commonly used public DNS, such as 1.1.1.1, 8.8.8.8, or 223.5.5.5, then restart the client and try again. Windows users can also open Command Prompt and run ipconfig /flushdns to clear the cache.
In clients such as Clash Verge, FlClash, and sing-box, you can also check whether the DNS settings have been changed incorrectly. If you’re not sure, restore the default settings first, then import the subscription. Don’t run multiple proxy apps at the same time, as their DNS and system proxy settings may conflict and cause subscription updates to fail.
Check your browser and client environment, too
Some subscription links involve redirects. If the link opens in your browser but won’t update in the client, the issue may be related to the user agent, certificates, or system time. Make sure your system time and time zone are correct. If you have packet-capture tools, certificate managers, or ad blockers installed on your computer, try temporarily disabling them. On a phone, try switching your default browser and copying the full subscription link again.
- Clash clients: Delete the old subscription configuration and add it again; don’t just overwrite its name.
- V2RayN: Right-click the subscription group and select “Update subscription.” If it fails, check the log for details.
- sing-box: Make sure the configuration file hasn’t been edited incorrectly and that you’ve pasted the subscription link in the right place.
Finally, if only one subscription won’t update while others work, the subscription source is probably temporarily unavailable or the link has expired. If none of your subscriptions will update, start by checking your local network, DNS, system proxy, and security software. Testing each item above should help you identify why your subscription link won’t update.
