Trying to break openvpn?

Question

openvpn

For a long time I observe in the logs attempts to somehow get into my VPN server

May 26 05:32:46 Servak ovpn-tcp[21135]: TCP connection established with [AF_INET]216.218.206.67:2156

May 26 05:32:47 Servak ovpn-tcp[21135]: 216.218.206.67:2156 SIGUSR1[soft,connection-reset] received, client-instance restarting

But here's how they try to get in if the authorization is by certificates?
Does it make sense to panic and do something, or can you score?

Answer 1

And this is not your client with the wrong settings?
If not, score.
