Hello @fmemon,
welcome to the Nextcloud community! ![]()
likely there is an issue with Collabora:
sounds it can not start properly for some reason. I would recommend to restart/recreate the collabora container and if it doesn’t help look if some permisssions or security settings brake it
UPD:
- there was similar issue some time ago Updated Collabora, container starts but later stops
- there is also a relevant discussion Problems getting collabora docker container working - User Support - Collabora Online
