Since upgrading to the Nextcloud 3.0.0 iOS app, all of my files have vanished from the app and every time I load it I get a 500 Internal Server Error banner showing in red in the app every time I load it.
This makes the app mostly useless - however it does seem to be autouploading my photos still, so it’s clearly not totally broken.
No logs are showing up in my Nextcloud admin console related to this problem at all.
All other clients, including Windows, Linux, and Web|CalDAV access via GNOME are all working fine.
I have tried resetting the App
I have uninstalled and reinstalled the App
I have toggled both “Most Compatible” and the new “Live Photo” features
At the time of installing the app I was running latest Nextcloud 18.x (using the Docker Containers, following the standard docker-compose method with mariadb, php-fpm and nginx)
I tried upgrading to Nextcloud 19.x with no change to the situation.
And all of the above symptoms happen on both my iPhone and my iPad, when using WiFI or LTE.
Anyone with any clue how to get things working again?
