Icinga2 client and director connection issue


I have just installed a new Icingaweb2 with a Self-Signed Certificate with the director, everything seems work well. I have also already integrated Linux clients via nrpe as in previous versions.

Our Windows clients I would like to connect with the Icinga agent, but have the following problem with the setup issue (Setup via Framework with the Kickstart Script):

PS C:\Users\Administrator> Use-Icinga;
PS C:\Users\Administrator> Start-IcingaAgentInstallWizard `
>>     -DirectorUrl            'https://IP or FQDN/icingaweb2/director/' `
>>     -SelfServiceAPIKey      'e53db0aff5d1sdfgsdfgsdgsdfgsdfgb6ed8904' `
>>     -UseDirectorSelfService 1 `
>>     -OverrideDirectorVars   0 `
>>     -Reconfigure `
>>     -RunInstaller
[Error]: The remote host for address "https://IP or FQDN/icingaweb2/director/self-service/powershell-parameters?key=e53db0aff5d1sdfgsdfgsdgsdfgsdfgb6ed8904" could not be resolved
[Error]: Failed to connect to your Icinga Director at "https://IP or FQDN/icingaweb2/director/". Please try again
Please re-enter your SelfService API Key for the Host-Template in case the key is no longer assigned to your host (Defaults: "e53db0aff5d1sdfgsdfgsdgsdfgsdfgb6ed8904"):

The Host-Template has been self created in the director incl. API-KEY:
