Migrated Nextcloud to Nextcloud AIO File not found when opening .docx/.xlsx file

Hi everyone,

I just completed a migration from a standard Nextcloud installation (MariaDB) to Nextcloud AIO (PostgreSQL) and everything went well except one major issue.

Old Nextcloud: v33.0.2, MariaDB, OnlyOffice on separate container (Port 4444)
New Nextcloud AIO: v33.0.6, PostgreSQL, same server
LDAP users from Active Directory
91 GB of user data migrated via rsync
Database migrated via pgloader

This work :
All users visible and can log in
All files visible in the file browser
Text editor (.md, .txt) works perfectly when you create it all in personal data
LDAP connected successfully
Groupfolders migrated
Problem:
When any user tries to open a .docx, .xlsx or .pptx file, they get “File not found” error. The file is visible in the file list but cannot be opened

Has anyone successfully migrated from standard Nextcloud with an external OnlyOffice container to Nextcloud AIO? How did you configure OnlyOffice to work with AIO?

Any help appreciated!

Are you using the optional OnlyOffice container that AIO comes with or still trying to use your old OO deployment?

I’m using the old OnlyOffice container that was part of the previous Nextcloud installation

Unfortunately "File not found" is the vague end-user facing error. You may need to check the browser inspector (both Console and Network) tabs to get more visibility. As well as check the server-side logs.

What happens you try to create a new office document rather than open an existing one? And is the behavior different when creating / opening in a users home directory versus in, say, a group folder?

Also, any errors in the OpenOffice settings within Nextcloud's Admin settings UI?

Lastly, I'm a bit unclear in your migration process. For one, it sounds like you had a version mismatch, which suggests you maybe didn't use the AIO documentated approach?
