I am using Ubuntu 22.04. Suddenly, my VPN is disconnected. My VPN stays connected for less than a minute, then it gets disconnected. I have tried most of the solutions.
solution 1: trying to run my OpenVPN file
sudo openvpn --config vpnbook-us1-tcp443.ovpn
Solution 2 : Can't connect to VPN after upgrading to Ubuntu 22.04
Solution 3: 22.04 l2tp client not working
nothing worked for me.
