This article addresses the common question, “Why won’t free nodes connect?” If the same node works for others but times out for you, the cause is often not just an expired node, but may also involve your local IP network, DNS resolution, or browser proxy environment. The troubleshooting steps below are arranged in a practical order for ordinary users and apply to clients such as V2RayN, Clash Verge, sing-box, and Shadowrocket.
1. First confirm that the node itself and the subscription are working properly
Free nodes are usually shared by many users, so their stability can fluctuate. Before troubleshooting locally, start with basic checks to avoid repeatedly tinkering with your own device.
- Open the client and manually update the subscription, or re-import the free node subscription provided on this site.
- Make sure details such as the node protocol, port, UUID, and Reality/TLS settings were copied completely and correctly.
- Run a “speed test,” “latency test,” or “connectivity test” in the client.
- Test 2–3 nodes from different regions or with different protocols instead of focusing on just one node.
If all nodes show a timeout, the problem is more likely with your local network or proxy settings; if only one specific node fails, that free node is most likely temporarily unavailable.
2. Your IP network environment can affect whether it connects
A very common reason why free nodes won’t connect is that your current network exit is restricted. For example, company networks, campus networks, and hotel Wi-Fi may block certain ports, and mobile carrier networks and broadband networks may also differ in availability.
- Switch between Wi-Fi and a mobile hotspot to test whether the current network is restricting access.
- Turn off features such as “parental controls,” “security protection,” or “ad filtering” on your router, then try again.
- Restart your modem or router, obtain a new public exit IP, and then reconnect.
- If your client supports it, try nodes using different transport methods such as TLS, Reality, or WebSocket.
Note: it is not recommended to repeatedly turn the client off and on and immediately run speed tests, because some networks temporarily cache failure states. Wait 30 seconds before trying again.
3. DNS resolution errors can make a node appear to be down
Many node addresses use domain names rather than plain IPs. When DNS resolution is abnormal, the client may be unable to find the server, showing symptoms such as connection timeouts, handshake failures, or lookup failed in the logs.
It is recommended to use relatively stable DNS servers in the system or client, such as 223.5.5.5, 119.29.29.29, or the client’s built-in remote DNS. Clash users can check whether DNS is enabled in the configuration; sing-box users can check in the graphical client whether the DNS policy has been altered incorrectly.
Do not run multiple proxy tools at the same time. For example, running V2RayN, Clash, and a browser proxy extension simultaneously may cause DNS requests to be handled by different programs, resulting in proxy loops or resolution failures.
4. The browser environment can also cause “connected but won’t open” issues
Sometimes the client shows as connected, but the browser cannot open web pages. In most cases, this does not mean the node has completely failed, but rather that there is a conflict involving the browser proxy, cache, or extensions.
- First open the test website in an incognito window to rule out cache and Cookie issues.
- Disable extensions such as SwitchyOmega, ad blockers, or privacy protection tools, then try again.
- Check whether the browser is set to use its own separate proxy; it is recommended to change it to “use system proxy.”
- Clear the browser’s DNS cache; in Chrome, you can visit chrome://net-internals/#dns to clear it.
If Telegram and the YouTube client work, but only the browser does not, focus on checking the browser environment; if all software fails, go back to checking the client logs and network environment.
5. How to quickly identify where the problem is
You can troubleshoot in this order: update the subscription and switch nodes; switch to a mobile hotspot; change DNS; close other proxy software; test with another browser or in incognito mode. This process covers most free node connection failure scenarios.
It is normal for free nodes to be unstable. It is recommended to bookmark multiple backup nodes and update subscriptions regularly. If the logs show timeout, the cause is usually that the network or node is unreachable; if you see DNS or lookup, check DNS first; if it shows connected but web pages will not open, check the browser and system proxy first.
