I got this hint in t3.german already and found:
ERROR [HTMLArea.Iframe::getStyleSheets]: A security error occurred. Make
sure all stylesheets are accessed from the same domain/subdomain and using
the same protocol as the current script.
[HTMLArea.Iframe::getStyleSheets]: Stylesheets not yet loaded

as the BE is accessed in https, the css is requested also by https. 
but there is a redirecting on the server which redirects

and again
and again
