Nextcloud 10.2.0 and SMB Shares -> Collabora not working

Steps to reproduce

1. Sign in to Nextcloud
2. Go to an SMB-shared directory
3. Try to open/edit document

Expected behavior

Document should open for edit

Actual behavior

Collabora is launched, but either an error message regarding corrupted files is displayed (Read-only share) or a blank document (no contents) is shown (Read-write share)

Other information

Host OS: Ubuntu 24

Other valuable info

We are using the all-in-one docker version of nextcloud (version 10.2.0) and we have attached two external SMB shares, one as read-only and the other as read-write. The files are accessible within the nextcloud platform and we can download and/or upload them accordingly. The shares have being attached using a password locally-stored within the DB.

When we try to edit (or view) the files however using Collabora, we get two different kinds of errors...

For the Read-only share:

Regarding the SMB Read-write share however, the behavior is totally different:

In both cases, however, either Collabora launches with an error being displayed regarding "corrupted files" (R/O case), whereas in the latter case (RW share), Collabora opens the document but its contents are empty.

Only files that are stored within the local Nextcloud storage can be opened/edited by Collabora, at this time.

Any help? ;)

No repository file or test is named. Start by reproducing document opening from both read-only and read-write SMB shares, then compare the richdocuments WOPI and Collabora logs shown in the report. Done means documents stored on either SMB share open with their contents and the read-only case does not report corruption.
