RDS VDI creation error: The provisioned virtual machine could not connect to its primary domain

In a lab environment I am creating a VDI infrastructure based on Windows Server 2019 servers.
After creating a template the creation of VDIs fails with the error:

Failed:the provisioned virtual machine could not connect to its primary domain
Where can I locate a step-by-step guide to create and publish a Windows 10 based template?
