Hello Jochen Schissler
Glad to know that your issue has been resolved.
Initially, you were unable to deploy the server in West Europe region, with the error message,
The resource write operation failed to complete successfully, because it reached terminal provisioning state 'Failed'. Provisioning in requested region is not supported.
In further investigation, we attempted to enable the region level access, and you were able to deploy it.
I hope this has been helpful!
