As in the title mentioned I have problems with previews for jpg pictures. I changed my setup from apache server (with php and mysql) on a Raspberry PI to nginx (with php and mysql) on docker running on a QNAP with the following details
Nextcloud version: 15.0.7.
Operating system and version: Alpine Linux 3.9.3 on Docker
nginx version: 1.15.10
PHP version: 7.1.27 (fpm)
The following problems appear:
- slideshow does not show jpg files, but shows png files
- in theme app I can not set a background picture (neither jpg nor png)
- the file app shows previews for png files (but as the slideshow app no jpg files)
The problem appears after my change to docker. Everything else is working. I already checked the requirements (https://docs.nextcloud.com/server/15/admin_manual/installation/source_installation.html). All required modules + recommended + exif + imagick are installed and enabled. Everytime I try to open a jpg file it does not work.
Here is the output of the log file:

Other webapps beside nextcloud are working and show jpg files. If I convert a jpg file to png on commandline with “convert picture.png picture.jpg” I get no error.
