I've faced an issue not showing preview when implement live streaming serviced by Azure.

I created a new live event and streaming endpoint in Azure.

But in frontend, when implement live streaming in Video player, it shows following error in previewing.

I logged response from network in inspect of Chrome. It responses like the following:

<serverError>
  <status>404</status>
  <subStatus>1000</subStatus>
  <hresult>MPE_STORAGE_RESOURCE_NOT_FOUND</hresult>
  <activityId>8000AEAC-0801-EC00-B63F-84710C7967BB</activityId>
  <serviceId>AAEBACDE-F9BE-44F5-8FE5-A55BB39AC182</serviceId>
</serverError>

Anyone can resolve this issue?
