This article addresses a common question: “Why can’t I connect to free nodes?” Often, the node itself hasn’t necessarily stopped working. Your local IP status, DNS resolution, browser proxy settings, or client configuration may be interacting in a way that prevents a connection. Follow these troubleshooting steps in order; they’re suitable for everyday users and work with clients such as Clash, V2Ray, VLESS, and sing-box.
1. First, check that the node and client are working
Free nodes can become temporarily unavailable because of heavy usage, maintenance, or restrictions imposed by the destination website. Don’t troubleshoot using just one node. Start by running the client’s built-in latency test or trying 2–3 nodes in different regions. If they all fail, check your local environment next.
- Make sure your subscription is up to date: click “Update Subscription” or “Refresh Configuration” in your client.
- Check your system clock: a significant time difference can cause TLS handshakes to fail.
- Close any duplicate proxy software: don’t run multiple VPNs, accelerators, or proxy clients at the same time.
- Check the mode: in Clash, try “Rule” or “Global” mode; in sing-box or V2Ray, make sure the system proxy is enabled.
We recommend using the free nodes on this site in the following order: update your subscription, test latency, then connect and browse. Avoid relying on a single node over the long term.
2. Your IP environment can affect connection success
One person may be able to connect to a free node while another cannot, possibly because of the local network’s public IP. For example, campus networks, corporate networks, and some public Wi-Fi networks restrict non-standard ports or proxy traffic. Home broadband may also trigger a destination site’s security checks if you’ve switched proxies frequently.
To check, try connecting to the same node over your phone’s mobile data. If it works on mobile data but not over Wi-Fi, the problem is probably with your current network. Try restarting your router, switching to a 4G/5G hotspot, choosing a different node port, or temporarily avoiding the restricted network. Note that being unable to connect to a free node doesn’t mean your client is broken. Testing another network is the quickest way to find out.
3. Incorrect DNS settings can also leave you “connected but unable to browse”
Many users see their client report a successful connection but still can’t open Google, YouTube, or other websites, or find that pages load very slowly. In these cases, check DNS. DNS translates domain names into IP addresses. If DNS responses are tampered with or cached incorrectly, access may fail even when the proxy connection is working.
- On Windows, run ipconfig /flushdns in Command Prompt to clear the cache.
- In Chrome, visit chrome://net-internals/#dns to clear the browser’s DNS cache.
- Clash users can try enabling built-in DNS and choosing fake-ip or redir-host as required by their configuration.
- Avoid entering different DNS servers in your system, router, and client at the same time, as they can conflict.
If only some websites are inaccessible, clear the DNS cache, restart your browser, and try another node. If no websites open, check the proxy port and system proxy settings.
4. Browser settings can also make it seem as though the node isn’t working
Browser extensions, proxy add-ons, and privacy extensions can change how your traffic is routed. For example, SwitchyOmega or certain ad-blocking extensions may override your client’s proxy settings, so your browser doesn’t use the VPN. Try testing in a private window or a clean browser profile.
Follow these steps: disable browser proxy extensions; clear your cache and cookies; make sure the client has taken over the system proxy; then visit ipinfo.io or a similar IP lookup page to see whether your public IP has changed. If it hasn’t, your traffic isn’t going through the proxy. If it has changed but websites still won’t load, check DNS or node availability. Remember, a successful connection, a changed IP, and a working webpage are three separate steps.
5. Quick troubleshooting checklist
If you can’t connect to a free node, follow these steps in order: update your subscription, try another node, switch networks, clear the DNS cache, disable browser extensions, restart the client, and finally reinstall the configuration. Don’t repeatedly reinstall the software as your first step; that usually won’t fix IP or DNS issues. If multiple free nodes remain unavailable for a long time, your subscription source may have expired or your current network may impose strict restrictions. Try a different working subscription and test outside peak hours.
