Inactivity timeout (--ping-restart), restarting - but only on one interface

Teddy · Aug 4, 2020, 8:46 AM

Hello together,
since a few days I am having following problem:
I have setup two ovpnc interfaces, which connect to a public VPN Service (CG), but irregularly i get the inactivity timeout (--ping-restart), restarting on the first ovpnc interface. The second ovpnc interface works for days without any disconnect, completely stable.
So i changed the servers (ovpnc1 austria -> ovpnc2 ; ovpnc2 switzerland -> ovpnc1), to crosscheck, if the VPN service is maybe the problem. But the problem remained on ovpnc1. Still on this interface the Inactivity timeout.

Any more ideas i could try, to resolve this issue? The reconnect happens now 5-6 times every day! Worked for months without any problems and disconnects, but now, suddenly, happens again and again.
