Promox 4.2 running on 2 nodes + 1 quorum = total 3 servers.
All of them have tinc vpn running.

On very rare occasions (every few days or 1~2 weeks), my website hosted on this proxmox node will throw cloudflare 522 connection timed out: https://support.cloudflare.com/hc/en-us/articles/200171906-Error-522-Connection-timed-out

This problem has been driving me crazy. I'm not sure, but I suspect this is caused by tinc vpn that somehow got disconnected.
