This article addresses the question, “Why can’t I connect to free nodes?” In many cases, the node itself hasn’t necessarily stopped working—the problem may be a conflict between your IP environment, DNS resolution, browser proxy settings, or client configuration. The steps below are ordered for everyday users and apply to common clients such as V2Ray, VLESS, Clash, and sing-box.
1. First, check that the node and client are working properly
Free nodes are often heavily used and may not stay available for long. If a connection fails, don’t keep reconnecting to the same node. Start with these basic checks:
- Check whether your phone or computer can access domestic websites normally to rule out a general internet outage.
- Make sure the client’s time matches your system time. A significant time difference can cause TLS verification to fail.
- Copy the subscription or node link again, making sure no characters, spaces, or line breaks were missed.
- Update the subscription in your client, then test a recently updated node with low latency.
- If only one node fails, try another node from the same subscription. If they all fail, check your network environment using the steps below.
We recommend using the free nodes on this site by updating your subscription, testing latency, and switching nodes as needed, rather than sticking with the same node long-term.
2. Your IP environment may prevent a connection
The same node can behave very differently on different networks. Common issues include restrictions on proxy connections at work, on campus, or on hotel Wi-Fi, as well as temporary carrier network issues. Try the following:
- Switch from Wi-Fi to mobile data, or vice versa.
- Turn off other VPNs, accelerators, and game proxies to avoid routing conflicts.
- Restart your router or switch networks, then try connecting again.
- If the client reports a timeout or connection refused error, try a different node or network first.
Keep in mind that free nodes are shared by many users, and some exit IPs may be blocked by the websites you’re trying to access. In that case, the client may show that you’re connected, but webpages still won’t load or you may see frequent CAPTCHA challenges.
3. DNS and browser settings can also affect access
Some users assume that “connected” means every website should open, but DNS and browser settings can also cause apparent connection problems. If only some websites fail to load after connecting, check your DNS settings. With clients such as Clash and sing-box, an incorrect DNS configuration in rule mode may cause overseas domains to be resolved locally, preventing access.
For your browser, check three things: whether a proxy extension is installed, whether the browser’s built-in Secure DNS is enabled, and whether there is stale cached data. Try an incognito window or test with another browser, such as Chrome, Edge, or Firefox. If other apps can connect to the internet but your browser can’t, the problem is most likely in the browser settings, not the node.
4. Recommended troubleshooting steps
- Update your subscription and test two or three different nodes.
- Check the client’s proxy mode. If you’re new to this, start with global or rule mode, and don’t run multiple proxy apps at the same time.
- Switch network environments, such as between Wi-Fi and a mobile hotspot.
- Remove browser proxy extensions and test in an incognito window.
- Check your DNS settings and, if necessary, restore the client’s default DNS settings.
- Look for keywords in the logs, such as timeout, TLS, DNS, or refused, and troubleshoot accordingly.
If the logs show TLS, certificate, or handshake errors, the node itself or a configuration mismatch is likely to blame. If they show DNS errors, check name resolution first. If the connection succeeds but webpages still won’t load, focus on browser proxy settings and rule-based routing.
5. Tips to avoid running into the same problems
When using free nodes, consider keeping multiple subscription sources and updating them regularly. Don’t assume that an unavailable node means the client is faulty, and avoid repeatedly uninstalling and reinstalling the client. It’s more effective to check each layer in order: node, network, DNS, and browser. Once you identify which layer is causing the problem, it’s usually quick to figure out why free nodes won’t connect—without blindly switching software.
