Problem with creating CMG

Seyed Majid Taheri 46

Hi guys,

I get following error when I create CMG (ConfigMgr 2409).

(Code: ResourceDeploymentFailure, Target: /subscriptions/23d6d-2924e2c502e8/resourceGroups/providers/Microsoft.Compute/virtualMachineScaleSets/extensions/InstallCMG)

How can I solve this issue?

Have you registered the Microsoft.compute resource provider in your subscription?

Yes, I've registered Microsoft.Compute, Microsoft.Storage, Microsoft.Network and Key.Vault.

I realized that I never responded to you. If you are still facing the issue then have a look in the operational logs for the CMG VM in Azure. It may a case of Azure resource creation policies in your tenant that may be stopping the creation of CMG resources.

Hi, @Seyed Majid Taheri

Thank you for posting in Microsoft Q&A forum.

May we know which step do we get this error? Have we checked the related logs for more details? Such as CMG-<cloud_service_name>-ProxyService_IN_0-CMGSetup.log, CloudMgr.log, CMG-<cloud_service_name>-ProxyService_IN_0-CMGService.log, SMS_Cloud_ProxyConnector.log on the server side.

Thank you for reply.

I got following errors in CloudMgr.log

ERROR: Exception occured for service : Azure.RequestFailedException: The table specified does not exist

"displayStatus": "Provisioning failed",~~ "message": "VM has reported a failure when processing extension 'InstallCMG'

and following error in SMS_Cloud_ProxyConnector.log when I have installed CMG connection point:

ERROR: Failed to build HttpV2 connection with server . Exception: System.Net.WebException: Unable to connect to the remote server --->

but I can ping it.

Failed to build HttpV2 connection with server.

This error in the SMS_Cloud_ProxyConnector.log suggests that there is a connectivity issue between your CMG connection point and the remote server.

Even if you can ping the server, there may be firewall rules or network security groups that are blocking the necessary ports for HTTP/HTTPS traffic. Ensure that the required ports are open and that there are no network restrictions preventing the connection.

I think that error is because the CMG has not yet been fully provisioned.

I have turned off firewall on SCCM server but I still get that error.
