This article addresses a common question: “Why can’t I connect to free nodes?” Often, the node itself isn’t necessarily down—the connection may fail because of your local IP network, DNS resolution, client settings, or browser environment. The steps below are ordered for everyday users and apply to common clients such as V2Ray, Clash, and sing-box.
1. First, determine whether the problem is with the node or your local environment
Free nodes are often shared by many users, so their availability can fluctuate. If a connection fails, don’t keep clicking the same node. Try switching between 2–3 nodes in the same client. If they all fail, the issue is more likely to be your local network, DNS, or proxy mode. If only one node fails, it’s probably temporarily unavailable or experiencing high latency.
- Make sure your phone or computer can access domestic websites normally.
- Update the subscription in your client to avoid using an outdated configuration.
- Test nodes in different regions and using different protocols.
- Check that your system clock is accurate. The wrong time can interfere with TLS connections.
We recommend importing the subscription for the free nodes provided on this site before testing them. This helps avoid omitting fields such as the port, UUID, or encryption method when copying them manually.
2. IP network issues: switch networks before drawing conclusions
Some network environments restrict proxy connections, including corporate networks, campus networks, and public Wi-Fi. There may also be temporary issues with your carrier’s network. In these cases, errors such as “timeout,” “connection refused,” or a failed handshake may be related to your current IP egress.
Here’s how to troubleshoot: switch from Wi-Fi to mobile data, or from mobile data to your home broadband. If the connection works immediately after switching networks, the node may be fine—the problem is with the original network environment. You can also restart your router to obtain a new public IP. Reconnecting to some home broadband services may help. Avoid running multiple proxies, accelerators, or security software with network filtering enabled at the same time, as they may conflict.
3. DNS issues: check DNS if you’re connected but websites won’t load
Many users assume that seeing “Connected” in the client means they can access the internet. However, DNS issues can prevent webpages from loading or domains from resolving, or make some websites accessible while others aren’t. In particular, mismatched rule modes and DNS policies in Clash or sing-box can make a connection appear successful even when access fails.
- Use the DNS settings recommended by your client, and avoid mixing multiple configurations arbitrarily.
- If you use Clash, try switching from “Rule” mode to “Global” mode for testing.
- Clear your system’s DNS cache, or restart the client and browser.
- Turn off Secure DNS/DoH in your browser and try again to avoid conflicts with the client’s DNS.
A simple rule of thumb: if you can access a site by entering its IP address but not its domain name, DNS is likely the problem. If all connections time out, the issue is more likely to be the node or network link.
4. Your browser environment can also affect access
Sometimes the client has successfully enabled the proxy, but your browser still can’t open the target website. Possible causes include cached data, extensions, leftover proxy settings, or an unusual browser fingerprinting environment. Try an incognito window first, then compare the results in another browser. Chrome, Edge, and Firefox don’t handle proxies and DNS in exactly the same way, so don’t rely on just one browser when troubleshooting.
If your browser has ad-blocking, privacy, script-management, or proxy-switching extensions installed, disable them all before testing. Windows users should also check whether old software has set an incorrect address for the system proxy. On macOS, check Network settings for any leftover HTTP/SOCKS proxies. If webpages still won’t load after you exit the client, the system proxy settings probably haven’t been restored.
5. Recommended quick troubleshooting steps
- Update the subscription and test 2–3 different free nodes.
- Switch to Global mode to rule out problems with rule-based routing.
- Switch networks: try Wi-Fi or mobile data, or restart your router.
- Restart the client, clear the DNS cache, and turn off Secure DNS in your browser.
- Try another browser or an incognito window, and disable any suspicious extensions.
In summary, being unable to connect to free nodes is usually related to one of four factors: node availability, IP network restrictions, DNS resolution, or the browser environment. Following the steps above can help you pinpoint the issue quickly. If multiple nodes fail across multiple networks and clients, consider switching to a new subscription source or waiting for the nodes to be updated.
