Remote Icinga instance is not connected to Icinga Master

one yer later…
I am experiencing similar issues…

Icinga Web 2 - 2.8.2
director - 1.7.2
Agent - Icinga2-v2.12.0-x86_64.msi

my question: Colin mentioned he executed the powershell kickstart script from director host - agent page… is this still necessary? im asking because i cant find this step in the documentation under “Agent Setup On Windows”
i tryed it on one of my test Clients… didnt work out really… do i need to adapt something in the srcipt?

What does the script do?
