What VPN client is known to work?

I’m new to Manjaro Phosh, and am excited about how fast it is on my Pinephone. I’ve been working to make sure my few usual-apps are working (I’m coming from Mobian). I’ve run up against a tough one:

What VPN client is known to work?

I tried manually configuring NordVPN on CLI - it wouldn’t connect. I’ve tried ProtonVPN’s UI client - it just sat spinning forever. I tried NordVPN’s command-line client - it connected once, but then has failed ever since - despite trying UDP, TCP, re-logging-in, etc.

I’m using a fresh install without adding any firewalls. I was using the DEV release, so I’m working on installing BETA16 to try. I’m working on installing BETA16 to try, but if someone knows of a working VPN (and maybe has some notes on how to set it up), that’d be great!
