Ubuntu 18.04 Login window loop

Is there any reason the login window would stop working and start looping? I'm running 18.04. I normally RDP into the ubuntu box, but that isn't working now. Using a keyboard and mouse, I see my username on the monitor. I type in my password. Then the screen goes blank for a few seconds... and I'm back to the login screen where my username is. I'm not getting through to my desktop!



I haven't messed with the machine except for the following, but, I'm not sure why any of these would impact the loginscreen.






But none of these messed with the login manager. Does anyone have any idea what could be up? Interestingly, nearly all of my docker containers (portainer, heimdall, tatulli, sonarr, radarr, pihole) work, with the exception of anything using ssl (plex and cockpit). I'm guessing somehow the firewall blocked port 443, but I'm not sure why that would stop me from logging into the box using a keyboard and mouse...



Any help/insight is greatly appreciated!



EDIT1: I tried creating another user via



sudo useradd -d /home/testuser testuser  

sudo passwd testuser


but the login manager still throws me for a loop



EDIT2: I've disabled the firewall via



sudo ufw disable



and I reversed the system-resolved.service work, but still no luck :(
