IC2 appliance - Error after upgrade to

First sign of trouble is at the sign in screen. The image which is usually displayed is broken:

I can see that the image is trying to load from https://“my.ic2.fqdn”/api/system/cover. However I seem to get a 502 Bad gateway for anything under /api/.

I am able to log in, but i only get error messages like theese:

Here is some of the information displayed in the control panel:
