Look in the monitoring log in the Azure resource group and thar should give you more details on which Azure policy is blocking the configuration. This might help https://rahuljindalmyit.blogspot.com/2019/10/cloud-management-gateway-resource.html

Dear Team,
We are creating CMG VMSS using the existing Azure ServerApp and it finishes the CMG installation wizard. However, in the cloudMgr.log the errors are showing it is failing due to policy violation. Please see the below log information.
Please note we have registered the service providers in new subscription as Microsoft.Keyvault, Storage, network and compute as manually.
Kindly let us know how we can resolve this issue further. Please help us here if you have seen anything similar like this during the setup.
