This article addresses the question, “Why can’t I connect to free nodes?” In many cases, the node itself hasn’t necessarily failed; the issue may be a conflict between your local network, DNS, proxy rules, browser environment, or client configuration. Follow the troubleshooting steps below in order. They apply to common clients such as Clash, V2Ray, and sing-box.
1. First determine whether the problem is with the node or your local setup
Because free nodes are publicly shared, they may experience temporary congestion, rate limiting, changes to their entry IP, or maintenance downtime. Don’t focus on just one node when troubleshooting. Instead, run a few cross-checks: try 2–3 nodes in the same client; try the same node on a different network, such as switching from Wi-Fi to a mobile hotspot; and visit different types of websites, such as a search page, a video site, and a developer site. If only one node fails, it’s probably temporarily unavailable. If they all fail, the cause is usually your local setup or client settings.
- Make sure your system clock is correct. An incorrect time can cause TLS handshake failures.
- Check that your subscription is up to date. Don’t keep using an outdated configuration.
- Close any other proxies, accelerators, or old VPNs to avoid port conflicts.
- Check the client logs for messages such as timeout, DNS, handshake, or connection refused.
2. How your IP, DNS, and browser environment can affect the connection
Your IP environment can affect your chances of connecting. Some broadband, campus, and corporate networks restrict UDP, proxy ports, or unusual TLS traffic, causing nodes to time out. If this happens, try a mobile hotspot. If the connection works there, your original network is likely restricting it. You can also switch to a different node protocol or transport type in your client, but avoid running multiple proxy tools at the same time.
DNS is another common cause. If your system DNS is being tampered with or resolving slowly, the client may show as connected while webpages fail to load, or some sites may work while others don’t. Try enabling the client’s built-in DNS or its “remote DNS/proxy DNS” option. If you use Clash, check that DNS is enabled, and avoid routing all DNS queries through an unreliable local DNS server. After making changes, remember to restart the client and refresh the browser page.
Your browser environment can also lead you to the wrong conclusion. Browser extensions, ad blockers, privacy extensions, and proxy extensions may override the system proxy. Browser caches can also retain an earlier failure state. Try testing in a private window or using another browser, and make sure the client is correctly controlling the system proxy. If the client shows that the connection is successful but the browser still can’t access websites, check the browser’s proxy extensions and DNS cache.
3. Step-by-step fixes for free nodes that won’t connect
- Update your subscription: In the client, click “Update Subscription/Refresh Configuration” to make sure you’re using the latest nodes. We also recommend updating before each use of the free nodes provided on this site.
- A latency test doesn’t guarantee the node is usable: A latency result only shows that the entry point can be reached. You still need to open a webpage or use the client’s connectivity test to confirm the connection works.
- Switch modes: Clash users can test “Rule/Global/Direct” mode to make sure the rules aren’t sending the target website through a direct connection.
- Check the proxy port: Make sure the browser or system proxy port matches the port the client is listening on, and that no other software is using it.
- Clear DNS: On Windows, run ipconfig /flushdns. On a phone, turn Airplane Mode on and off, or restart the network.
4. What to do if it still doesn’t work
If the connection fails across multiple nodes, networks, and browsers, try uninstalling or resetting the client, then import the subscription again. Don’t manually change fields such as the UUID, port, encryption, or transport parameters during import, as this can easily cause a handshake failure. Free nodes are suitable for temporary learning and emergency use, but their reliability depends on the number of users and network conditions. If a node becomes unavailable, follow the troubleshooting steps in this article first, then wait for an update or switch to another node.
