Unable to access my Plex Server on UNRAID

Starting this AM, I am unable to access my Plexserver. It is installed under a docker on UNRAID. Has been working fine until today. This morning was stuck on Starting Plex media server but would not load completely and my apps could not find the server.
I tried reinstalling the image after deleting it completely, but was stuck in same “starting plex media server” so finally I deleted the appdata folder, and reinstalled the official plexmedia server on docker. I was finally able to load up the server completely without any errors.
but now I cannot reach my server and the webapp can’t find it - it keeps looking for servers.

I also followed the help section for is your server locked? Edited the preferences.xml and also deleted the preferences.xml file. I tried to load locally as well but didnt work.

I have tried everything to make it work, but am getting frustrated! up until today everything was working fine.

I have attached the server logs as well
