When OpenClaw suddenly disconnects and throws an error code, many users feel lost. As a daily proxy tool, OpenClaw frequently encounters issues like connection timeouts and authentication failures—but with the right approach, you can fix them in minutes. This article breaks down four high-frequency error codes and shares practical, tested solutions.
Connection Timeout: Check Node & Local Network
If you see "Connection timeout," first confirm whether your selected node is online. Run a latency test in the client's node list. If the node responds to ping but still times out, your local firewall or antivirus software is likely blocking the proxy port. Temporarily disable Windows Defender or 360's network protection, then try reconnecting. If the issue persists, switch to a node with lower latency and ensure your network isn't restricted by your ISP (corporate networks often block ports).
Authentication Failed: Update Subscription or Re-enter Key
"Authentication failed" usually means your subscription link has expired or the key is incorrect. Log in to the OpenClaw official website, copy the latest subscription link from your user dashboard, and reimport it into the client. Note that older client versions may not support V2Ray format—update to the latest version. Also, check your system time; a time deviation of more than 5 minutes can cause TLS handshake failure. Sync your computer's clock to resolve this.
