A new subscription was added to an existing tenant in Azure, and a new host connection was created for it in Citrix Cloud. A MCS machine catalog failed to be created due to the following error.

DesktopStudio_ErrorId : ProvisioningTaskError
ErrorCategory : NotSpecified
ErrorID : Finished
InternalErrorMessage : Error: Provisioning failed Subscription XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX was not found.
DesktopStudio_PowerShellHistory : Create Machine Catalog 'XXXX'

 

Register the resource provider "Microsoft.Storage" in the subscription, Azure Portal -> [Subscription] -> [Resource Providers].

---

Problem Cause

The issue occurs when the resource provider "Microsoft.Storage" in the subscription is in "NotRegistered" status.
In the creation of a MCS machine catalog a storage account is created. To check and create a storage account, the Citrix Cloud uses API for "Microsoft.Storage". If it is in "NotRegistered" status, the error occurs in handling the storage account.
