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

Upgrade owncloud to nextcloud
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.

I'm seeing the exact same behavior (no thumbnails in either the nextcloud or owncloud apps after upgrade to nextcloud 9.0.5). Likewise, the nextcloud app gives me thumbnails as normal with an older owncloud installation. The only point I'll add is that both apps continue (for me) to display thumbnails that had already been fetched prior to the server upgrade, so that's worth watching out for while trying to repro.

I guess I have an idea. Assigning to myself. Thanks for reporting this back to us! :-)

Thanks a lot for reporting this bug again.

Could I ask you to test the patch in #110? Only the changes in the file lib/private/appframework/http/request.php are relevant. It would be awesome if you could test on your instance whether that would work. 🚀

Fixed via #110 in 9.0.51
