This article addresses the common question, “Why won’t free nodes connect?” Often, it’s not that the nodes are necessarily down; the issue may be that your IP, DNS cache, browser proxy settings, or client rules aren’t configured correctly. The steps below are arranged in an order that most users can follow, and apply to clients such as Clash, V2Ray, VLESS, and sing-box.
1. First, determine whether the problem is with the nodes or your local environment
Free nodes are often shared by many users, so their reliability can fluctuate. But when troubleshooting, don’t focus only on the nodes. Start with a simple check: if none of the nodes in the same batch can connect, the problem is more likely to be your client, network, or DNS environment. If only a few nodes fail, those nodes may have timed out, be congested, or be incompatible with your configuration.
- Check that your system clock is correct. An incorrect time can cause TLS handshakes to fail.
- Update your subscription and select a node again instead of continuing to use an old cached one.
- Test using both mobile data and Wi-Fi to see if your current broadband connection is the issue.
- Check your client logs for keywords such as timeout, TLS, DNS, or connection refused.
We also recommend updating the subscription before testing the free nodes provided on this site, to avoid importing outdated links into your client.
2. Your IP environment can affect connection success
Many users overlook their local outgoing IP. Some network environments restrict proxy protocols, ports, or connections to overseas servers, resulting in very high latency, failed speed tests, or disconnections shortly after connecting. Restrictions are especially common on campus networks, corporate networks, and public Wi-Fi.
Try the following: close the client, restart your router, or switch networks. Mobile users can toggle airplane mode to obtain a new mobile network IP. If the connection fails on a corporate or school network, try using your phone as a hotspot. If the hotspot works but your original network doesn’t, the issue is most likely with your current network’s outbound connection, not the client itself.
3. DNS errors can make it seem like you’re connected when you can’t access websites
DNS translates domain names into IP addresses. If a node connects but webpages won’t load—or only some websites are inaccessible—a common cause is DNS pollution, a corrupted cache, or the client not handling DNS requests. Clients such as Clash and sing-box usually include DNS settings, and differences in rules can also cause resolution issues after importing a configuration.
- First, enable global mode in the client to rule out problems with your routing rules.
- Clear your browser’s DNS cache, or simply restart the browser.
- On a computer, restart the network adapter; on a phone, toggle airplane mode.
- If your client supports DNS options, use the settings included in its configuration and avoid changing them at random.
Note that DNS issues don’t always show up as a “connection failure.” More often, the proxy connects but webpages remain inaccessible.
4. Your browser and system proxy settings may also conflict
If the client shows that it’s connected but your browser still can’t open webpages, check whether the browser is using the correct proxy. Some browser extensions, ad blockers, and outdated proxy extensions can override the system proxy, causing the client to work normally while the browser does not.
Try testing in an incognito window and temporarily disabling proxy-related extensions. Then check whether the client has “System Proxy” or “TUN Mode” enabled. Windows users can also check the system proxy settings for an old port that may still be configured. If only one browser is affected while other apps work normally, focus on the browser’s cache, extensions, and security software.
5. Quick troubleshooting checklist
- Update your subscription and test 2–3 different nodes.
- Switch to global mode to check whether the issue is caused by routing rules.
- Switch networks: test both Wi-Fi and your phone’s hotspot.
- Restart the client, browser, and network connection.
- Check the logs and use messages such as timeout, DNS, and TLS to identify the issue.
In summary, free nodes that won’t connect may be down, or the problem may be caused by your IP, DNS, or browser environment. Troubleshooting in this order—update your subscription, switch nodes, switch networks, check DNS, and check your browser proxy—will usually help you pinpoint the issue quickly.
