Can't sign in to ProtonVPN

I installed proton-vpn for the GUI and tried signing in a handful of times, manually typing in my user name or email, and password, but it said invalid credentials. I tried the CLI (proton-vpn-cli) as well and got the same error.

I think you should add your user to the networkmangergroup. That worked for me.

I already have networkmanager in my list of extraGroups.

Can you loggin to email on your browser?

If you use the free version of proton then it restricts VPN to one device.

I suggest you only put one proton VPN app in your config for now,

Any other issues? And is your system up to date?
The proton VPN used to be a pain but now its usually good.
