@circ @domubpkm Hey so I'm having the same error code with my Ubuntu Phone VPN connexion.
I changed username and password to avoid non alphanumeric characters.
Do the name and location of .ctr and .key files have any sort of importance?
ca.crt has the form:
and ta.key has the form
-----BEGIN OpenVPN Static key V1-----
-----END OpenVPN Static key V1-----
Both are extracted from the xxx.protonvpn.com.udp.ovpn file downloaded on my protonVPN account.
Could the gateway port number be an issue?
Do you have any idea why it still doesn't work?
Thanks a lot for any kind of help or suggestion!
Edit1: Note that the password is always missing when I open the VPN editor app, but that could also just be some kind of security. Is that the expected behavior?
