Problem:
After installation of the id-connector you get an empty api page
Investigation:
You have installed the id-connector with the manual
https://docs.software-univention.de/idbroker-school-authority-manual/installation.html
but after the installation you cannot access
https://<Server-FQDN>/ucsschool-id-connector/api/v1/docs
You only get an empty page.
Solution:
This is because, at the moment the UI of ID-Connector and Kelvin loads external resources (JS and CSS) from cdn.jsdelivr.net. so you have to allow cdn.jsdelivr.net on your proxy or firewall until Bug 56329 or Bug 56314 (kelvin-api) is fixed
