Actually, i don’t know why do you need to use app itself.

I moved to native NetworkManager client (especially perfectly working on “user friendly” distros).

This eliminates many issues (including this), because when using native tool, you can draft a FW rules yourself.

On other systems there is reason to use app, on Linux - there is already a built-in tool for OpenVPN and Wireguard.
