Frequently asked questions
AI-generated answers based on this skill's SKILL.md and metadata
Why is my Cloudflare Tunnel down?
Cloudflare Tunnel Troubleshoot systematically identifies root causes of tunnel outages. Start by checking container status and verifying your tunnel token is valid and current. Review logs for Error 1033 (authentication failures) or QUIC protocol issues. Use the provided diagnostics to confirm connectivity between your origin and Cloudflare's edge, then apply targeted recovery commands to restore remote access.
How do I fix Cloudflare Tunnel issues?
Cloudflare Tunnel Troubleshoot guides you through structured resolution steps. First validate tunnel tokens and container health. Analyze error messages and connection logs to pinpoint failures—common culprits include QUIC incompatibilities, timeouts, and authentication errors. The skill provides recovery commands and configuration checks to restore connectivity without manual trial-and-error.
What does tunnel connection failed mean in Cloudflare?
Cloudflare Tunnel Troubleshoot explains that connection failures occur when your tunnel cannot establish or maintain a link to Cloudflare's edge. This blocks remote access to your origin. Causes include invalid tokens, container crashes, network timeouts, or QUIC issues. The skill's diagnostics isolate the exact failure point and recommend fixes—whether restarting containers, refreshing credentials, or adjusting network settings.
How can I troubleshoot Cloudflare Tunnel errors?
Cloudflare Tunnel Troubleshoot provides systematic error diagnosis. Check tunnel status and review logs for specific error codes like Error 1033. Validate your tunnel token hasn't expired. Confirm container is running and network connectivity is stable. The skill analyzes QUIC protocol issues and connection timeouts, then delivers targeted commands to resolve each error type and restore tunnel health.
What should I check if my tunnel won't connect?
Cloudflare Tunnel Troubleshoot recommends checking container status first—ensure the tunnel daemon is running. Verify your tunnel token is valid and not expired. Review connection logs for timeout or QUIC errors. Confirm network routes allow outbound traffic to Cloudflare endpoints. The skill's diagnostics pinpoint whether the issue is local (container/config) or network-based, then guide you to the appropriate fix.
How do I perform a Cloudflare Tunnel health check?
Cloudflare Tunnel Troubleshoot includes built-in diagnostics to assess tunnel health. Check container status and verify the tunnel daemon is active. Validate authentication tokens and test connectivity to Cloudflare's edge. Review logs for Error 1033, QUIC failures, or timeouts. The skill's health checks confirm whether your tunnel is online, responsive, and properly routing traffic—and recommend recovery steps if issues are detected.
