[Solved] Raspberry PI4 and VPN error login

[peppect84]

Good evening, I'm trying to start an openVPN client ".ovpn" with relative user and password but I get these errors

the user and password are correct, I can't explain why it can't connect to the vpn

Since its non interactive mode the user and pasword need to be stored in a file. OpenVPN then needs to be informed of this file by adding the complete path to the file to the auth-user-pass setting.

auth-user-pass /etc/openvpn/adminIT.auth

Also you should fix the warnings reported in the first two lines. Apparently whoever wrote the .ovpn file was using an old version of OpenVPN.

I added this line to the file but the result hasn't changed

You added it to the user pass file. That is wrong, that file must be only two lines: your user name on the first line and password on the second line.

In the .ovpn configuration file, change the line that is now just auth-user-pass to include the filename.
