Why won’t my free node connect? This guide helps you tell the difference between a failed node, client settings, network IP issues, DNS problems, and browser issues. Follow the steps in order: confirm the connection, check name resolution, then troubleshoot the browser. This helps you avoid repeatedly switching nodes without finding the cause. Free nodes can change availability quickly, and updating a subscription does not mean every server will work.
1. First check whether the node has failed or the client isn’t routing traffic
Open your Clash, V2Ray, or sing-box client and confirm that the configuration has loaded and a specific node—not “Direct”—is selected. On a computer, check that the system proxy is enabled. On a phone, confirm that you’ve allowed the app to create a VPN connection. Run only one proxy client at a time to prevent another VPN or proxy tool from taking over your traffic.
- Update the subscription and check whether it succeeds. If you get an error, first check that the subscription URL is complete and hasn’t expired. Don’t rely solely on whether the nodes still appear in the list.
- Test the latency or connectivity of the selected node, then visit two different websites. A latency result doesn’t guarantee that a webpage will load, so also check actual access and the connection logs.
- Try a different route. If only one node fails, suspect that it may be down, congested, or restricted. If all nodes fail, check your local settings.
- Turn on automatic date and time on your device. A significant clock offset can cause certificate validation to fail.
2. How your IP and network environment affect the connection
Distinguish between the node server’s IP and the public IP used by your current network. If the server IP is unreachable, the service has been shut down, or access is restricted, the connection may time out. Your network’s public IP—whether you’re on Wi-Fi, mobile data, or a public network—may also be subject to connection restrictions. A timeout alone doesn’t prove that an IP has been blocked; cross-test first.
Keep the same node and configuration, then test over both Wi-Fi and mobile data. If it fails only on one network, check whether that network requires you to sign in through a webpage or has access restrictions. If it fails on both networks while other nodes work, the original node is more likely to be the problem. Don’t disable your firewall right away; first check whether security software is blocking the client.
3. How to check for DNS issues
If the client appears to be connected but webpages show “server not found” or the logs report a resolution failure, DNS may be the issue. First exit the client and check whether ordinary domestic websites open. Then restore the DNS settings recommended by the client and reconnect. Don’t change DNS in your system, client, and browser all at once, or it will be difficult to pinpoint the cause.
Change only one setting at a time, then test before deciding whether to keep it. The browser’s “Secure DNS” setting may use a different resolution path from the client. Temporarily turn it off to compare, and restore it if that doesn’t help. Don’t rely on visiting a website by its IP address as your only test, since HTTPS certificates and website hosting configurations can affect the result.
4. What to do if only the browser won’t load websites
If other apps work, first test in a private window, then temporarily disable proxy-related extensions. Check whether the browser has its own proxy settings. Some extensions may remain enabled in private mode. If only one website is affected, clear that site’s cache and cookies; there’s no need to clear all your browsing data.
If the website loads but shows a CAPTCHA, denies access, or reports that your region doesn’t match, the site is usually restricting access based on your public IP, account, or browser environment. This doesn’t mean the node failed to connect. You can try another node for comparison, but that may not remove the restriction. If the issue persists, note the client version, error message, and results on different networks. Before asking for help, redact sensitive information such as your subscription URL and UUID.
