CasaOS running but WebUI broken

Hi all,

Complete computer novice. Had CasaOS set up on a raspberryPi for a plex server. Ran sudo apt update and upgrade through the CasaOS terminal. I can still SSH into my Pi from Power Shell and have confirmed CasaOS is running but the WebUI won’t load. I have read it may have to do with firewalls blocking the port but I find this unusual as I have never had any issues. Would appreciate any assistance.

Could you try to run a health check?
