Promox 4.2 running on 2 nodes + 1 quorum = total 3 servers. All of them have tinc 1.0.24 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 for few seconds or few minutes: 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. root@node1pve:/# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 4.00 KByte (default) ------------------------------------------------------------ [ 4] local 192.168.xxx.xxx port 5001 connected with 192.168.xxx.xxx port 13394 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.1 sec 1.02 GBytes 868 Mbits/sec root@node2pve:/# iperf -c node1pve ------------------------------------------------------------ Client connecting to node1pve, TCP port 5001 TCP window size: 45.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.xxx.xxx port 13394 connected with 192.168.xxx.xxx port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.02 GBytes 876 Mbits/sec root@node3pve:/# iperf -c node1pve ------------------------------------------------------------ Client connecting to node1pve, TCP port 5001 TCP window size: 45.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.xxx.xxx port 55336 connected with 192.168.xxx.xxx port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.06 GBytes 907 Mbits/sec /etc/tinc/vpn/tinc.conf: Name = node1pve AddressFamily = ipv4 Device = /dev/net/tun Mode = switch ConnectTo = node2pve Digest = none Cipher = none What should I do?
