Question

I am trying to deploy a MySQL instance into a VNET with private DNS in a different subscription.

It is failing with the error: "The subscription '

Answer 1

Hello ,
I had the same problem with MySQL Flexible Server .
The deployment was failed with following error :

{
    "status": "Failed",
    "error": {
        "code": "InvalidPrivateDnsZoneSubscription",
        "message": "The subscription 'XXXXX-XXX-XXXX-XXX-XXXX' of the private DNS zone 'privatelink.mysql.database.azure.com' is in valid, it is not registered for '2'."
    }
}

To resolve it , the unique provider to register is Microsoft.DBforMySQL on Private Dns Zone subscription.
Thanks

Answer 2

I managed to resolve this myself by adding the following Resource Provider registrations to the subscription containing the private DNS zone:

Microsoft.DomainRegistration

Microsoft.DBforMySQL

Unfortunately I don't know which one fixed it because I applied them both at the same time, but hopefully this helps someone else who encounters the same problem!
