No Thumbnails with nextcloud on android-apps

I upgraded my owncloud 9.0.2 installation to nextcloud 9.0.5 today, and everything seems to work just fine, with the exception of thumbnails in the android app.
I only encounter this error when using my nextcloud-installation, and only with the android apps (the nextcloud-app, the owncloud-app and the Cirrus-app all have this issue)
.
If i use another server (for example the owncloud demo-login), or another way to see the thumbnails (for example in the browser, or via the owncloud ipad-app) everything works fine. because the combination naxtcloud-android-app -> owncloud-demo-server gives me thumbnails, i figured it's not an androuid-app problem, but a server-issue
### Steps to reproduce
1. Upgrade owncloud to nextcloud
2. Access the server via android app
### Expected behaviour

Thumbnails of uploaded images should appear
### Actual behaviour

instead of a thumbnail every image has the placeholder-image as thumbnail
### Server configuration

**Operating system**: Debian Jessie

**Web server:** Apache 2.4

**Database:** mysql

**PHP version:** 5.6.20

**Nextcloud version:** 9.0.50 (stable)

**Updated from an older Nextcloud/ownCloud or fresh install:** updated by unpacking the .tar-file, copying over the /data folder and the /config/config.php file, and editing the apache-config to fit the new path. also edited the data-path in the config to the new path. on first visit, nextcloud upgraded itself, and everything just worked

**Where did you install Nextcloud from:** https://download.nextcloud.com/server/releases/nextcloud-9.0.50.tar.bz2

**Signing status (Nextcloud 9.0 and above):** what is this?

```
No errors have been found.
