If only they would focus a bit more on Linux compatibility. It is very tedious to use protonvpn on headless Linux distros. Their protonvpn cli is not supported for raspbianOS.
True, the Linux app (both the old and the new one) sucks to the point, where I gave up and just put my Linux PC behind a network-wide VPN (which is set up using a Wireguard profile)
Can you share your set up info? I am currently using it on my rpi on which i have a torrent client. I am using the wireguard profile which i need to connect each time using wg-quick up <wireguard conf>
It doesn't persist through system reboots and port forwarding is also very tedious on cli using natpmpc.
Looks fantastic on Android (at least in that screenshot) and amazing on Windows, but looks like something I'd be programming in the one Python class I took on Linux.
