NVIDIA Deep Stream SDK Module is Backoff in Azure

I use the NVIDIA Deep Stream SDK for IoT-Real time stream analyzing on a Jetson Xavier device using the tutorial in https://news.developer.nvidia.com/deepstream-sdk-debuts-on-microsoft-azure-marketplace/

When I select “start monitoring built-in event endpoint” it does not show anything. The NVIDIADeepstreamSDK in Azure portal is backoff. The microsoft technicians told me that I have to contact NVIDIA for this problem.
