Error - "No space left on server"

Nothing saves on Collabora anymore - it keeps telling me there no space left on the server. This is absurd as I have over 100gigs of space left on my server and Nextcloud has no problem creating and saving new files there.

I have no idea where to start debugging because I can’t figure out where the Collabora logs are or where it’s making its disk space determination. Does anyone know? Thanks.

sudo du -hxd 4 / | sort -h

Literally the whole thing? I use Webmin so I can see I have 15.02gig used of 25.78gigs free on my Nextcloud server and over 130gigs free on the data drive for my server. I don’t lack space but Collabora incorrectly thinks I do and I can’t figure out why or how to even start debugging.
