Hey everyone,

I’m running into a frustrating issue with OnlyOffice and external shares, hoping someone here might have seen this before.

My setup

- Nextcloud version: 31.0.12

- OnlyOffice app version: 9.11.0

- OnlyOffice Document Server: Docker container

The problem:

When I share Excel files via external share (public link/email), people can’t open them in OnlyOffice. They get the error: “You don’t have enough permissions to view the file”

The weird thing is:

- When I’m logged in as a user, Excel files open perfectly fine in OnlyOffice

- PDFs shared externally work without issues (they don’t use OnlyOffice)

- The share permissions are definitely set to “Read” and “Edit”

So it seems like OnlyOffice just doesn’t want to work with external/anonymous users, even though everything looks configured correctly.

Has anyone else experienced this after updating to Nextcloud 31.0.12?

This is a known bug with this version combination?

Any suggestions would be really appreciated! This used to work fine before, so I’m a bit stumped.

Thanks in advance!

Solution was to update to OnlyOffice App version 9.12.0
