External storage images thumbnail not generating until viewed in mobile app

Nextcloud version : 26.0.0
Operating system and version : Deb 11
Apache or nginx version : Apache 2.4.56
PHP version : PHP 8.1.17

The issue you are facing:

When uploading images to the external storage via the web interface, the thumbnails are not generating. But then if you go in the android app, it triggers the thumbnail generation and they appear on the web after a refresh.

If I upload an image from windows and let the client sync it, it also doesn’t generate a thumbnail until I open the android app.

In the external storage settings, “enable preview” is checked.

What would prevent the web panel from making the thumbnail generation?


Best regards


Anyone has a similar issue occurring? Should I submit that on the github issues instead?


I just saw it was submitted on github:
