I've been randomly having issues today with PIA, can confirm that it was working well yesterday. My docker config uses ouroboros to auto update, and it looks like DelugeVPN latest was updated last night.
Several troubleshooting steps, but the one that worked was to revert to what looks like the previous build in docker. Can confirm that binhex/arch-delugevpn:2.0.4.dev38_g23a48dd01-2-15 works.
