New-Skills: Keycloak forwarding on integration

[ManuelMoeri]

When I press the Sign in with Keycloak Openid button it just redirects me on a completely blank page. It also does not work with the Login text in the top right corner.

I've also tried to open it in a private Window. I freshly logged in yet nothing changed. Even stranger that it works for @Robin481 I don't have a clue how or why.
