Appcenter not working

I have installed UCS (UCS 5.0-1 errata187) and everything seems to be working except for the appcenter.
When i go from the portal to the appcenter i get a black screen with a red square with the message Error.

When i update via univention-app update i get the following message:
Downloading “https://appcenter.software-univention.de/meta-inf/app-categories.ini”…
Error

Logs are giving the following messages:

Can anyone help me to make the appcenter work.

It has something to do with ssl i discovered. if i changed the hardcoded site from https to http it seems to work but it destroyed my entire installation. I had to reinstall and that created the logs as specified.

I hope that someone can help me to solve this matter.
