File/Emote upload doesn't work, claims read-only file system

Description

Whenever anyone tries to upload files, this error appears:

 Error: EROFS: read-only file system, open '/var/lib/rocket.chat/uploads/xxxxxxxxxx' [ufs: cannot upload file] 

This is not due to missing write permissions for the folder, which have been set to 755 as the support suggested.

root@xxxxxxxxx  ~ # ls -lisa /var/lib/rocket.chat 
total 188

Has anyone encountered the same error and if so, how did you fix it? Official support hasn’t been able to help so far.

Thanks!
