I have a server from my university, I used a vpn to connect to this server. The VPN was located on this server. To connect to this server , I used an OpenVPN .ovpn file with the configuration as follows:
# student.ovpn
client
dev tun
proto tcp
remote my.best.server.ip 443
resolv-retry infinite
nobind
#user nobody
#group nogroup
persist-key

On September 5th, my server's certificate expired and my website is unavailable. To update this certificate, I have to connect to the server. But I can't do it because the server is only accessible via VPN and I can't connect to VPN:
$ openvpn student.ovpn

Is there any way I can update my .ovpn file or accept an insecure (expired) certificate to gain access to my server?
