Fritz.Box Binding fails when executing switch, scan or simliar

I was able to great a proper configuration which shows bridge and a fritz dect 200 plug are online.
When I execute the switch on my sitemap the following error appears in log and the thing etc. show status offline. If I open the thing and store same configuration, things show green online status.
