provisioning a hostpool join domain failed - azure

Question

I'm totally new to azure, my intention was to test a bit to validate if worth or not.
My goal would be to virtualize a desktop at the moment just for introduction reasons.
So, I started an azure free account, followed the first steps to start an azure AD Domain service, afterwards I tried to add a new ressource to create a vm with provisioning a hostpool.
It failed giving me an array joindomain provisioning failed.
I did it just via the portal following the azure documentation til create a tenant, I of course used also the PS commands, afterwards I followed the introduction to create a hostpool.
I used a new ressource group and the existing vnet.
Here also the script the portal gave me for downloading:

And this is the error in extensions/joindomain

"displayStatus": "Provisioning failed",
"message": "ERROR - Failed to join domain='cheyenneitoutlook.onmicrosoft.com', ou='', user='chris#cheyenneitoutlook.onmicrosoft.com', option='NetSetupJoinDomain, NetSetupAcctCreate' (#3 meaning 'User Specified'). Error code 1355"

}
]
Any help with explaation what I did wrong is appreciated.

Your VMS cannot find or connect to the Azure AD DS managed domain. Take a look to Connectivity issues for domain-join and Connectivity issues.
