I just upgraded from 27.7.8 to 26.7.9.
Before my OpenVPN connection was perfectly stable and now it is restarted every few minutes!
The OpenVPN logging shows this:
tcp6-server:80.187.xx.xx:23679 validation failed on peer_info line received from clientThis happens with the client in company Wifi and also via mobile connection.
it seems to happen every 90s
the issue is solved: there was still a parallel VPN connection from another client to the same user.
