OpenVPN timeout session

[dym8]

Hello.

I have an OpenVPN server and imported users from AD and  AD authentication and OTP. But every an hour user session is broken. Log says

openvpn[39817] user/8.22.8.11:59250 SIGUSR1[soft,ping-restart] received, client-instance restarting
openvpn[39817] user/8.22.8.11:59250 [UNDEF] Inactivity timeout (--ping-restart), restarting

openvpn[39817] user/8.22.8.11:59250 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

I made next:
- set Renegotiate time to 0
- insert keepalive 10 120 into an Advanced field

But there aren't any results with an user session. Every an hour session is out any way.

I assume OPNSense is providing the OpenVPN server, and the logs you posted are from this server side. Did you take a look into the client's log?

Is there an option to increase the log level? That might provide additional information about what causes the handshake to fail.

Did you set the renegotiation time to 0 only on the server side? I assume you would need to configure this on both sides (client and server) and otherwise, if the client has a renegotiation time of 60 minutes configured, the client will trigger a renegotiation after 60 minutes, even if the server has this disabled.

Yeah, You was right. I added this line into .ovpn file and it fixed a problem
reneg-sec 0
