Hi,
Let me start by saying I’m new to Nextcloud. I’m experimenting to see if it would benefit my immediate family to share files, calendars, lists, etc.
However I’ve run into a problem with my setup and I’m not sure it’s a bug (or missing feature) with Nextcloud, Nextcloud Office, or Collabora, or if it’s a mistake on my part in my configuration. I would definitely appreciate some guidance to find out what part is failing, as well as help debugging and resolving the issue.
The problem is documents stored in external storage (SMB/CIFS) cannot be opened with Nextcloud Office. I get the infamous “Document loading failed. Try again later.”
Documents stored in regular Nextcloud folders open/edit/save without issues. I am also able to access, modify or delete files of all kinds on the external storage otherwise; whether by the web interface, the android app, or the Collabora android app.
The only somewhat relevant issue/thread I could find is Editing files with Collabora doesn't work on external storages · Issue #3407 · nextcloud/android · GitHub… but it applies to the android client, and is closed. I also verified that it works for me.
My client setup:
- Desktop running Ubuntu 20.04.4 LTS
- Firefox 102.0+build2-0ubuntu0.20.04.1
My server setup:
- Ubuntu 20.04.4 LTS
- Nextcloud 24.0.2.0 (manual install from zip)
- Nexcloud Office App 6.1.1
- Apache 2.4.41-4ubuntu3.12
- PHP 7.4.3-4ubuntu2.12
- Collabora docker, (re)installed 2022-07-12 using the nextcloud/vm collabora_docker.sh script: COOLWSD HTTP Server 22.05.3.1
- User configured External Storage SMB/CIFS with “Log-in credentials; save in session”
- External storage is a shared folder on a Helios4 NAS running openmediavault (Debian 11 Bullseye)
- No issues or security warnings in NC Adminstration Overview
- A+ security rating on scan.nextcloud.com
- The Nextcloud Office app reports the Collabora Office server is available
Docker logs: (no other logs, NC, Apache contain anything useful)

If there is information missing, please let me know. I tried my best to be thorough; but as mentioned earlier, I’m new to Nextcloud. Wouldn’t surprise me if I missed something.
Any help would be greatly appreciated!
