Running command 'icinga2.exe node setup --master_host mbmif.int.netways.de,5665 --endpoint mbmif.int.netways.de,mbmif.int.netways.de,5665 --accept-config --accept-commands --trustedcert "C:\Users\michi\AppData\Local\Temp\tmp1D62.tmp" --cn "DESKTOP-IHRPO96" --zone "DESKTOP-IHRPO96"' produced the following output:

critical

Needs a proper error handling for pending "no ticket" answers.
