The issue you are facing:
Can not access any files on NC server under any user after connecting ONLYOFFICE Community Server to NC account via WebDAV.
I set this Nextcloud server up for family use. My wife and I are the only 2 users, and I created an Admin user out of habit. I connected my account to my ONLYOFFICE account and all hell broke loose. The wife and I use the mobile apps for Android and iPhone, as well as the PC apps for Linux and Windows. They are all erring. When I connect to a folder from inside ONLYOFFICE, it shows zero contents. From inside Nextcloud, when clicking a file or folder, it gives the error: This operation is forbidden
I can see data in the data directory, when logged in via SSH, but server-side encryption is enabled, so viewing files to check for corruption or missing data is pointless.
Is this the first time you’ve seen this error? (Y/N): Yes
Steps to replicate it:
- Log into ONLYOFFICE Community Server
- Click Documents
- Add account (Nextclolud)
- Open Nextcloud web portal and attempt to enter any folder
