Cloudflare Tunnel Timeouts and QUIC Protocol Connection Issues
I'm experiencing persistent timeouts and connection issues with my Cloudflare tunnels across all endpoints. The error message displayed is:
“upstream->downstream copy: read tcp [::1]:36358->[::1]:8443: use of closed network connection.”
It seems that the issue is related to the QUIC protocol, as there are disruptions in the connection between upstream and downstream, causing the closed network connection error. Despite troubleshooting, including checking the tunnel configuration, restarting the tunnel, and testing two different SSL certificates (self-signed and Let's Encrypt), the problem persists. I also verified DNS settings, but the issue continues.
