Bug description

Steps to reproduce:

Nextcloud Server 25.0.x (Error exist since Update from 24.0.x to 25.0.x) PHP 8.1 PostgreSQL 15.1 ubuntu server 22.04.1 (as VM under vSphere 7)

My system integrated external storage via NFS Share as "local". (on a fileserver a nfs-server delivers space to nextcloud, that is mounted as nfs share to a local folder on the nextcloud server and offers this share as "local" external storage to NC Server)

Everytime i upload a PDF file to an external storage i get 4 errors in seconds

3 times Fatal onlyoffice Download without access right followed by 1 time Error onlyoffice Exception: Im Dokumentenservice ist ein Fehler aufgetreten: Error while downloading the document file to be converted.

My ONLYOFFICE Server is running as docker image on the same server, that hosts my NC Server. ONLYOFFICE is reachable under port 443 mapped to 8443 Settings for onlyoffice in NC Admin pages delivers a "green" feedback when saving my settings. pdf files are not tagged as supported filetype in onlyoffice settings!

The behaviour is reproducable. It concerned every allowed user and groupmember in my little cloud instance. (not more than 35 users at the moment)

ONLYOFFICE itself seems to work without failures. Users can create, edit office files. Users can check the status of the onlyoffice server by https://domain.onlyoffice.net

Steps to reproduce

1. see above

Expected behavior

Uploading pdf files to an external space / storage mounted (local, via smb ) should not cause onlyoffice to produce fatals or errors.

I uploaded pdf files to groupfolders -> without causing the errors / fatals I uploaded to my nextcloud space (internal storage) -> without causing the errors / fatals I uploaded to any external storage (in my case mounted storage as NFS share from fileserver) -> errors /fatals occur

In every storage saving / uploading / editing office files (saving / uploading pdf files) is possible without obviously errors for the clients.

Additional info

Uploading a pdf file via webdav (under linux i have used double commander to copy from local to remote dir) does not affect the error log! First time i open the uploaded file with the browser (webui of nextcloud) i see the error log filling with errors and fatals. There are no errors / restrictions on client side(!) - clients can open those pdf files correctly. But the server side logs errors / fatals every first time of opening the file after upload. Why this concerned "onlyoffice" - don't know?!

I haven't tested it yet, but i suppose that it will be the same behaviour when uploading a pdf via nfs / samba first and later opening the file via WebUI in a browser.
