This article addresses the common question, “Why can’t I connect to a free node?” When other people can use the same node but you can’t, the cause may not be the node itself. Your local IP, DNS, proxy mode, or browser environment may also be involved. The steps below are ordered for easy troubleshooting and apply to clients such as V2Ray, VLESS, Clash, and sing-box.
1. First determine whether the problem is the node or your local environment
Free nodes are often shared by many users and may not stay available for long. When a connection fails, don’t focus only on the client’s error message. Start with these three basic checks:
- Make sure your system clock is accurate. A large time difference can cause the TLS handshake to fail.
- Try another free node from this site or another source. If they all fail, the problem is more likely to be your local network or configuration.
- Check the client logs for messages such as timeout, DNS failed, TLS handshake failed, or connection refused.
If only one node fails, it’s usually temporarily unavailable, its port is blocked, or its configuration is no longer valid. If all nodes fail, continue with the checks below.
2. Your IP and network environment can affect the connection
Some networks restrict unusual ports or proxy connections, including corporate networks, campus networks, and hotel Wi-Fi. Try switching to your phone’s hotspot and connecting to the same node. If it works on the hotspot, the original network may have restrictions.
Also consider the status of your public IP address. Some free nodes may restrict unusual access patterns, frequent reconnections, or congested traffic from the same region. If this happens, restart your router, switch networks, or wait a while before trying again. Avoid repeatedly clicking Connect, as this may make the problem worse.
3. Incorrect DNS settings can also prevent you from connecting
Many users think DNS only affects web browsing, but proxy clients also use DNS to resolve server addresses. If DNS is being interfered with or resolution times out, the node may appear unresponsive.
- Clash users can enable DNS in settings and prioritize the DNS option built into the client.
- V2RayN and sing-box users can try changing the system DNS to 1.1.1.1, 8.8.8.8, or their ISP’s default DNS.
- If the subscription updates but the nodes won’t connect, the node domain may not be resolving correctly. If the subscription won’t update either, check your network and subscription link first.
After changing DNS, restart the client. If necessary, clear the system DNS cache before testing again.
4. Check your browser environment and proxy mode too
Sometimes the client shows that it’s connected, but your browser can’t open web pages. This doesn’t necessarily mean the node is faulty. Check that system proxy is enabled or that Clash is using the correct proxy mode. If you’re new to this, start with “Rule” or “Global” mode to confirm that pages load, then adjust the rules.
Browser extensions can also cause conflicts. For example, multiple proxy extensions, ad blockers, or privacy extensions may prevent requests from going through the client proxy. Try an incognito window or temporarily disable the relevant extensions. If only one browser fails, compare it with Chrome, Edge, or Firefox to narrow down the cause.
5. Recommended troubleshooting order
- Update your subscription or re-import the nodes to make sure you aren’t using an outdated configuration.
- Test 2–3 free nodes to rule out a single-node failure.
- Switch to your phone’s hotspot to check whether your current network is restricting the connection.
- Check DNS, system proxy, and client mode.
- Disable browser proxy extensions and test in an incognito window.
- Check the logs for keywords and continue troubleshooting based on whether they point to a timeout, DNS, or TLS issue.
In short, being unable to connect to a free node doesn’t necessarily mean “all the nodes are down.” More often, the cause is an unavailable node, a local DNS issue, network restrictions, or a browser proxy conflict. This site provides free node information that you can import, but availability can fluctuate. We recommend keeping multiple node sources available and learning to troubleshoot each part of your setup using the logs.
