I created a new account on OpenVPN Cloud and added a device to my account. Afterwards, I downloaded the profile file (.ovpn-file) and trying to establish the VPN connection using the following comment:

> sudo openvpn --config device_1_someuser\@somemail_com\@someuser.openvpn.com_Frankfurt.conf

But as you can see I'm the message "AUTH: Received control message: AUTH_FAILED,SSO Auth Failed due to lack of client support". I also already tried to use --auth-user-pass-parameter. But the error message remains to be the same. For the "--auth-user-pass"-parameter I used the parameters of my owner account (email address and account password). I hope that's correct but I'm not sure if I even need this...

Is anyone having any idea how I can solve this issue?

I was finally able to connect using OpenVPN. The problem was that I was using OpenVPN 2.4.7 but I had to use OpenVPN 3 instead.

  • I just installed openvpn3 but syslog tells me I'm using 2.5.1. How did you force it to use v3? – Eliot Jan 20 '22 at 10:49
