This article addresses the common issue of “subscription links not updating.” If clicking Update in clients such as Clash, V2Ray, or sing-box does nothing, times out, retrieves outdated nodes, or shows an empty configuration, follow the steps below to troubleshoot your network, IP, DNS, browser, and client settings.
First, check whether the subscription link is working
A failed subscription update doesn’t necessarily mean the client is broken. First, check whether the link is still accessible. Copy the subscription link into your browser’s address bar and open it. Normally, this may download a file or display a block of configuration text. If you see a 404 or 403 error, a certificate error, or an endless loading spinner, there may be a problem with the link, your network, or your access environment.
- Make sure you copied the entire link, especially any trailing parameters and special characters.
- Check whether the subscription has expired. Free-node subscription URLs may change periodically.
- Try copying the subscription link again from the latest free nodes page on this site.
- Don’t use a link to a sharing page as the subscription link. The client needs a URL it can use to fetch the configuration.
If the link opens in your browser but the client can’t update it, the problem is most likely related to the client’s proxy, DNS, or cache. If it won’t open in your browser either, continue by checking your IP and DNS environment.
How your IP and network environment affect subscription updates
Many subscription URLs have basic protections in place. Refreshing the same URL repeatedly from one IP address within a short period may result in a temporary restriction. Corporate networks, campus networks, and public Wi-Fi may also block certain domains. This can lead to connection timeouts, failed updates, or blank responses.
- Compare the results on mobile data and Wi-Fi.
- Turn off any active global proxy before updating the subscription, or try updating in “direct” mode.
- If your client supports “Update subscriptions through proxy,” try enabling it if a direct connection fails.
- Restart your router or switch networks, then wait a few minutes before trying again. Avoid clicking Update repeatedly.
Avoid refreshing subscriptions repeatedly in quick succession. This can trigger restrictions and may also cause the client to save a corrupted cache.
How to troubleshoot DNS and your browser environment
DNS resolution issues can prevent the client from finding the subscription domain, which may explain why the link sometimes opens in your browser and sometimes doesn’t. As a first step, try changing your system’s DNS to a common public DNS server, such as 1.1.1.1 or 8.8.8.8, or switch to your ISP’s automatic DNS settings, then test again. After changing DNS, clear the DNS cache. In Windows, run ipconfig /flushdns in Command Prompt.
Your browser environment can also affect the results. Open the subscription link in a private browsing window, and temporarily disable ad blockers, privacy extensions, and download managers. If your browser warns you about a certificate, first check that your system clock is correct. An incorrect system time can cause HTTPS certificate validation to fail, preventing the client from updating as well.
Common fixes in the client
Menu names vary slightly between clients, but the general approach is the same: clear the cache, re-import the subscription, and change the update method. For example, in Clash, V2RayN, or a sing-box GUI client, try these steps in order:
- Back up your current configuration and delete the subscription that failed.
- Paste the subscription link again. Avoid using special characters in its name.
- In Settings, switch between “Use proxy for subscription updates” and “Don’t use proxy.”
- Clear the configuration cache and restart the client.
- Update the client to a newer version to avoid compatibility issues with newer formats.
If the nodes are still outdated after updating, the client may be reading from a local cache. Don’t just click Refresh; delete the subscription and add it again. If you see a format error, the subscription content may not be in a format supported by your client. Use the subscription URL for the appropriate client—for example, a Clash subscription for Clash, or a universal or V2Ray subscription for a V2Ray client.
Quick checks if the problem persists
Here’s a quick way to narrow it down: if the link won’t open in your browser, check the link, IP, and DNS. If it opens in your browser but the client fails, check the client’s update settings and cache. If the problem occurs on only one network, it’s most likely due to network filtering or DNS resolution. If you’re wondering why your subscription link won’t update, don’t keep changing node settings at random. Troubleshoot in this order: link accessibility, network/IP, DNS, browser, and client. This will usually help you find the cause.
