Error when validating Azure Front Door migration

I am trying to migrate our Azure Front Door from classic to standard. During the validation process I get the following error.

Error condition: The subscription is not registered to use the {0} namespace.

It also displays the id (0bbb23a3-deca-4a05....) of the failed entity, which is our Subscription ID.

The "{0} namespace" is the most curious part of this. I have no idea what that is referring to.

Any help on this would be greatly appreciated.

Hello EddieB,

Thanks for your question.

This is a resource provider issue. Try register or re-register below providers you can use the following Azure CLI command:

az provider register --namespace Microsoft.Cdn
az provider register --namespace Microsoft.Network

Or via the portal:

1.	Go to Subscriptions > select your subscription.

2.	Under Settings, go to Resource providers.

3.	Search for and register the following:

Microsoft.Cdn

Microsoft.Network

4.	Wait a few minutes until their status shows Registered. 

You can mark it 'Accept Answer' and 'Upvote' if this helped you
