Clients lose connection and some stays down

iobelix

I have two Clients connected to a Server. All of them were working fine until both dropped the connection.

I see the usual "TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)" every 60 seconds but the server does not see any of this.

> sudo tcpdump -nnvvXXS dst port 1194
tcpdump: WARNING: eth0: no IPv4 address assigned
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes

^[[A^C
0 packets captured
0 packets received by filter
0 packets dropped by kernel
>

After few hours one of them connected, but the other is still trying to negotiate. All the server and clients are in the same network! And both the clients are sitting side-by-side! Here are the configs and journalctl logs.

What could be happening? Thanks
