Nextcloud version: 22.1.1
Operating system and version: Ubuntu 20.04
Apache or nginx version: nginx/1.18.0 (Ubuntu)
PHP version: PHP 7.4.3 (cli) (built: Aug 13 2021 05:39:12) ( NTS )
The issue you are facing:
First and foremost, I have been using Nextcloud since around version 12. It is great and I do love it, so “thank you” 
I have never been able to use the “Media” tab in the Android app. When I try to access “Media”, it indefinitely shows “Loading…”. I have included the output of the Nextcloud logs below, which seems to suggest that it doesn’t recognise me as being allowed access to my photos, despite being logged on as the same user (both in the app and on the PC).
I have a large collection of photos totalling 633GB, or 123K files. I can view them on my PC via the browser “/apps/photos/” but never on the Android phone app. I believe I have the latest app version, 3.17.1.
Is this the first time you’ve seen this error? (Y/N): No
Steps to replicate it:
- Open the Android app
- Select “Media”
- Stuck at “Loading…”
