What should you do if your subscription link won’t update? This guide helps you troubleshoot “update failed,” “download timed out,” and “no nodes after import” issues in clients such as Clash, V2Ray, and sing-box. It also explains how your IP, DNS, and browser environment can affect the process. Keep your existing configuration for now, and don’t repeatedly delete the subscription. Follow the steps below to find the cause more easily.
1. First determine whether the link has expired or the client is malfunctioning
- Open the subscription management page in your client and try updating manually once. Note the error message and when it occurred. Distinguish between a download failure, a parsing failure, and a successful update where the nodes are unavailable.
- Return to the subscription provider’s page and copy the full link again. Check that no trailing parameters are missing and that the link doesn’t contain spaces, line breaks, or Chinese punctuation. Don’t use a node-sharing link as the subscription URL.
- Check whether the subscription has expired, been reset, or requires you to sign in first. If the free nodes page on this site includes update instructions, follow the format and validity information shown on the current page.
- Make sure the link is compatible with your client. Some Clash configurations can’t be used directly with clients that accept only specific formats. Even if the download succeeds, you may still see a parsing error.
Subscription links usually contain access credentials, so don’t post them in public group chats, screenshots, or on unfamiliar online testing sites. If you need help, hide the path and parameters after the domain.
2. Check your current network and outbound IP
First, make sure you can open regular webpages. If you need to authenticate on public Wi-Fi, sign in before updating the subscription. Then try switching between Wi-Fi and your mobile hotspot. If the update succeeds on a different network, the original network’s DNS resolution, routing, or access restrictions may be contributing to the problem—but this alone doesn’t prove that your IP has been blocked.
If your client offers “direct” and “through proxy” options for subscription updates, test each one. When updating through a proxy, choose a node that’s still working; otherwise, you may end up in a loop where the update requires a proxy, but the proxy depends on an expired subscription. Change only one setting at a time and record the results. Revert any changes you no longer need after testing.
3. How to check DNS and your browser environment
If the logs show “domain name resolution failed” or “no such host,” check DNS first. Try reconnecting to the network and restarting the client, then switch to the system’s automatic DNS setting or a trusted DNS service. Your browser may use encrypted DNS, while the client relies on your system’s DNS or its own resolver. So being able to access a site in your browser doesn’t necessarily mean the client can resolve the domain too.
If the subscription URL redirects to a login page, CAPTCHA, or security check in your browser, the client usually can’t complete those interactions. First check your account and link status on the provider’s website. Don’t save webpage content as a subscription configuration. Browser extensions, cookies, and cache primarily affect webpage access and may not affect background updates in the client, so there’s no need to clear all your browsing data right away.
4. Complete these final checks based on the error
- Connection timed out: Check whether switching networks or changing the proxy used for updates helps. Try again later, and avoid sending repeated requests in a short period.
- 401, 403: This may involve credentials, permissions, or access restrictions. Check the provider’s instructions; changing DNS alone is unlikely to help.
- 404: Check the URL and confirm whether the link has been replaced or removed.
- Certificate error: Check your device’s date and time, and update the client. Don’t disable certificate verification without good reason.
- Parsing failed: Confirm that the response is a subscription rather than an error webpage, and check format compatibility.
If the problem persists, keep and back up your original configuration, upgrade to the client’s latest stable version, and test with a newly created subscription entry. A successful update doesn’t mean the nodes are working: if the subscription has downloaded normally, move on to troubleshooting node connections and routing. When contacting the provider, include the client version, network type, and a redacted error message.
