I use the following command to connect:

$ sudo openfortivpn -u "<user>" -p "<password>" <url> --trusted-cert <cert>

Do you think you can help me solve it? If you need more informations I would be happy to send them to you 🙏

Thanks in advance.

Maybe, I forgot to tell that everything was working perfectly until today, how should I change the MTU to test?
