Why can’t free nodes connect? This guide walks you through troubleshooting in the order of subscription, client, network, and node, and helps distinguish connection problems from account security checks. For team use, first determine whether the issue affects one person’s device or multiple users. This can reduce disruptions caused by repeatedly switching nodes or signing in again.
First, determine whether the node is down or your account is restricted
If the client times out and multiple websites won’t load, check the proxy connection first. If regular websites work but a platform asks you to verify your identity or reports an unusual sign-in, the node may not be the problem. A working proxy does not guarantee a stable account environment: frequent changes to your exit IP, region, or browser session may trigger platform verification, but you can’t identify the cause based on a prompt alone.
Free nodes may also be unavailable because of maintenance, traffic limits, expired subscriptions, or too many users sharing them. It’s not unusual for a node that worked yesterday to fail today, and one failed speed test isn’t enough to conclude that all nodes are down.
Check things in order to avoid reinstalling unnecessarily
- Confirm your local network is working. Temporarily turn off the proxy and open a website you can normally access directly. If it won’t load either, first troubleshoot your Wi-Fi, mobile network, or captive portal sign-in.
- Update your subscription. In clients such as Clash, sing-box, or V2Ray, find the subscription update option and check whether the update succeeded. If it failed, check that the subscription URL is complete and still valid. Don’t post it in a public group to ask for help.
- Confirm the import method. A single VLESS link and a full subscription are different types of content, so use the corresponding import option. If you see an unsupported field or configuration parsing error, check the client version and subscription format. Don’t change parameters at random.
- Select a node and test it by visiting a website. Check the latency first, then open the site you’re trying to access. A failed test address doesn’t necessarily mean all traffic is blocked. If you see a connection timeout or handshake failure, note the exact error and compare it with another node.
- Check that the proxy is handling traffic. Make sure the system proxy or TUN is enabled as required by the client, and avoid running multiple proxies, VPNs, or network filtering tools at the same time. If only some websites are affected, temporarily compare rule mode with global mode, then restore your original setting after testing.
- Retest on another local network. For example, switch from Wi-Fi to mobile data, keeping data usage in mind. If the same node fails on only one network, first check that network’s restrictions or DNS settings. You don’t need to reinstall the client right away.
For teams: use comparisons to pinpoint shared problems
Have two team members test the same node on their own devices around the same time, and record the client version, network type, and error message. If multiple people fail at once, check the node or subscription source first. If only one person is affected, start by checking their device, proxy settings, and software conflicts. Change only one variable at a time, or it will be difficult to tell what fixed the problem.
Teams can standardize the client source and troubleshooting notes, but don’t share platform account passwords, browser cookies, or complete logs containing credentials. Before sharing screenshots, hide subscription URLs, node authentication details, and personal information. When collaborating, share only redacted error messages.
Minimize disruption to your account environment
When handling account-related tasks, try to stick with your usual device, browser configuration, and a reasonably stable exit region. Avoid repeated sign-ins from different regions in a short period. If a node fails, stop retrying and confirm the connection is back before completing any verification requested by the platform. Don’t try to bypass security checks by frequently switching IPs.
The free nodes on this site can be used to practice importing configurations and test connectivity, but availability may change. Free shared exits should not be your team’s only connection option for critical work. For important tasks, have a compliant, reliable backup network available, and follow local laws and platform rules.
