deployment issue Cisco SD-WAN for Azure Virtual WAN

Question

hello,

i'm trying to deploy a Cisco C8000v in my vWAN/vHUB. i did it before but the new deployment gives an error: "The resource provider referenced in the action 'Microsoft.Deployments/*' is not returned in the list of providers from Azure Resource Manager."

under the vHUB i click the "Network Virtual Appliance", under "Third party providers".

Once i click the "create" for the "Cisco SD-WAN for Azure Virtual WAN", it generates the error.

"The resource provider referenced in the action 'Microsoft.Deployments/*' is not returned in the list of providers from Azure Resource Manager.

RAW ERROR, see below.

I tried to add "Microsoft.Deployments" under "Subscription> Resource providers", but it is not listed.

I hope somebody can help me out.

Thanks in advance
