ANSWERED Testing the connection in linux using openvpn CLI

[KovaKovi 4]

Hello!

I'm following this description (link) to make a VPN Proxy VM in Qubes OS. Unfortunately when it says to check the connection, i can't figure out how to do it. This is what i did and got an error:

1. In the VPN Proxy VM opened a terminal
2. The .ovpn file is here /rw/config/vpn/Airvpn_Europe_TCP-443-Entry3.ovpn
3. In the terminal from /home/user i use the command: openvpn --cd /rw/config/vpn --config Airvpn_Europe_TCP-443-Entry3.ovpn

Unfortunately i get an error:
Option error: Unrecognized or missing or extra parameter(s) in Airvpn_Europe_TCP-443-Entry3.ovpn:19: data-ciphers (2.4.7)
Use --help for more information.

openvpn version (debian-10): 2.4.7-1

I downloaded the .ovpn file like this:
Config Generator > choosing Linux as my OS, IPv4 only for IP layer exit and IPv4 as Connect with IP layer, tick the Advenced Mode, selecting OpenVPN version >=2.5, choosing OpenVPN TCP 443 tls-crypt, tls1.2 as the protocol and tick By Continents > Europe and finally generating and downloading the .ovpn config file, where i changed eurpe3.vpn... to europe3.all.vpn....

Could someone help me out how can i check the connection with openvpn CLI?

Thanks any help you can provide!

The error should be apparent to you, no knowledge required. You select OpenVPN version >= 2.5, yet your OpenVPN version is 2.4.7. The latter doesn't know the data-ciphers directive as it's new in 2.5.

Thanks @OpenSourcerer!

I just wanted to write that I realized my mistake...
