My PIA access has been working fine up until the last couple of days. It's not running 24/7 so I can't pin it down any closer than that.
I'm seeing the same behaviour as you, but have a log entry ' WARNING: file 'credentials.conf' is group or others accessible'. Working through troubleshooting right now. Randomly clicked the last item of this thread out of curiosity.
My installation is pretty old - I can see OVPN and certs have been updated by PIA. So possibly a good place to start.
** Update - updating OVPN and cert files fixed this for me. So maybe an easy place to start Burizado. Good luck.
