Azure Arc - 'NoRegisteredProviderFound' when attempting to access Windows Admin Center

Chris 5 Reputation points

I've had Azure Arc implemented in my environment for a while now - primarily used for Defender for Cloud. I have wanted to strengthen the capabilities of our Arc-enabled servers by enabling Windows Admin Center.

I onboarded a few with the AdminCenter extension yesterday (UK South), and all worked fine - I was able to connect in without an issue. However, when I try today - I get the message: 'No registered resource provider found for location 'uksouth' and API version '2021-05-20' for type 'endpoints'. The supported api-versions are '2021-10-06-preview, 2022-05-01-preview'.

I can confirm the resource providers Microsoft.HybridCompute/GuestConfiguration/HybridConnectivity are registered against the linked subscription which contains the resource group, I've tried unregistering and registering again.

Extensions running: AdminCenter (, MicrosoftMonitoringAgent (1.0.18067.0), MDE.Windows (, WindowsPatchExtension (1.5.59), AzureMonitorWindowsAgent ( Uninstalled/Installed and Offboarded/Onboarded both server(s) and extensions.

I've reviewed and packet captured firewall logs and can see no packet drops. The Arc-enabled servers are reporting back to Azure fine. Reverse Proxy is enabled too for the port 6516 with the Azure Connected Machine Agent.

Anyone seen this behaviour before? Doesn't seem to be much info online, thanks.

    Hello there,

    If Azure doesn't automatically register a resource provider, you can do a manual registration.

    This article describes resource provider registration errors that occur when you use a resource provider that you haven't already used in your Azure subscription. The errors are displayed when you deploy resources with a Bicep file or Azure Resource Manager template (ARM template).

    Hope this resolves your Query !!
