Nextcloud Docker Lockup

Hi Everyone,

i set this up in march and its been working flawlessly untill last week,

The Problem,

Nextcloud Docker Container Locks Solid, cant stop or restart it and i get 502 bad gateway when it locks, to get the container running again i have to litterally unplug my machine as this lockup stops unraid from soft rebooting,

im running 19.0.5 as thats the latest stable version via the updater,

nothing in the internal nextcloud log to show any sort of issue, nextcloud container log doesnt seem to show any issue either, but i do have some errors showing within only office and collabora,

Only office shows this:
[2020-12-07T15:01:48.460] [WARN] nodeJS - Express server listening on port 8000 in production-linux mode
[2020-12-07T15:01:59.771] [WARN] nodeJS - Express server starting…

Collabora shows this:

im at a complete loss here to be honest, so far options ive tried, ive changed the only office container as i thought maybe that was causing my initial lockups and it seemed to run for a day or 2 and then ive come to it again today and here we are,

when this issue started i was running nextcloud 18 i figured an update may solve any issues but again i was wrong.

any ideas im stuck and this is in a production environment with regularly accessed company data

any help appreciated
many thanks
