Hello
NC is uptodate and I did not succeed to display the HEIC files.
Neither in Files / Photo / Memories
To simplify the problem I try to generate a preview and it does not works :
sudo -u www-data php /var/www/nextcloud/occ preview:generate “user/files/Photos/2025/09-Home/IMG_8461.HEIC”

No provider successfully handled the preview generation
The check I have done (after looking in the forum) :
Change Imagemagik from 6.9 to 7.1
Check in config/config.php that HEIC is in the preview
Check that PHP-Imagick is link to imagemagik 7.x
Anyidea why the preview does not works ?
What mean
Invalid input: Unspecified: Too many auxiliary image references (2.0)
