This article addresses the question “Why can’t I connect to free nodes?” If the same node works for someone else but times out for you, the node may not be the only issue. Your local IP, DNS, browser proxy settings, or how you imported the node could also be to blame. Follow these troubleshooting steps in order.
1. First, check whether the node itself is working
Free nodes are often shared by many users, so congestion, speed limits, and temporary outages are common. Rather than repeatedly reconnecting to a single node, start with these basic checks:
- Make sure the node link is complete and that you’re importing it into a compatible client. Don’t import protocols such as VLESS, VMess, Trojan, and Shadowsocks into the wrong client.
- If you’re using a subscription, click “Update subscription” in your client, such as Clash, sing-box, or V2RayN.
- Test other nodes in the same subscription, preferably in different regions, so you don’t mistake a single-node outage for a software issue.
- Check that your system clock is accurate. An incorrect time can cause TLS handshakes to fail.
This site provides free nodes that you can import, but free resources aren’t guaranteed to remain stable. If a node stops working, try another one first.
2. Your IP or network environment may be preventing the connection
Some connection failures are related to the public IP address your network uses. For example, campus networks, workplace networks, and public Wi-Fi may block nonstandard ports. Some broadband providers may also be more restrictive during peak hours. Here’s how to check:
- Turn on your phone’s 4G/5G hotspot and try connecting from your computer.
- Test the same node over both your home Wi-Fi and mobile data.
- Disable any blocking features on your router, such as parental controls, ad filtering, or smart security, and try again.
If the connection works on another network, the node may be fine—the original network is likely blocking it. In that case, try nodes that use port 443 or more common obfuscation methods such as TLS/Reality.
3. DNS settings can also affect your connection
Many users assume DNS only affects website access, but clients may also use DNS to resolve subscription URLs, remote domains, and rules for traffic routing. DNS problems can cause subscription update failures, connection timeouts, or a successful connection that still won’t load websites.
Try changing the DNS settings in your client or operating system—for example, to 1.1.1.1, 8.8.8.8, or 223.5.5.5. For Clash-style clients, also check that DNS is enabled. In rule mode, it’s generally best to use the client’s built-in DNS to avoid DNS leaks or incorrect resolutions from your system DNS. After making changes, remember to restart the client and reconnect.
4. Check your browser and proxy mode
Sometimes the client shows that it’s connected, but your browser still can’t access external websites because it isn’t using the proxy. Common causes include conflicting browser extensions, a disabled system proxy, or rules that aren’t matching your traffic.
- Make sure “System Proxy” is enabled in the client. If you’re using Clash, switch to “Global Mode” as a test.
- Disable SwitchyOmega, ad blockers, and privacy proxy extensions to avoid conflicts between multiple proxy layers.
- Try Chrome, Edge, or Firefox to rule out browser cache or certificate issues.
- Visit an IP lookup website and check whether your public IP address has changed.
If Global Mode works but rule mode doesn’t, the issue is probably with your rules or DNS. If Global Mode also fails, go back to troubleshooting the node and network.
5. Quickly pinpoint the source of the problem
To save time, troubleshoot in this order: “node → network → DNS → browser.” A timeout usually points to a network or node issue; “DNS resolve failed” usually points to a DNS issue; and if the client says “connected” but websites won’t load, check the system proxy and browser settings. One final note: free nodes change frequently. If one fails, don’t keep refreshing the same node. Save a working subscription, update it regularly, and keep multiple clients on hand as backups to significantly reduce the chance of connection problems.
