Openvidu showing black screen when deployed on Azure

Hello, I am able to deploy openvidu in ubuntu server without any issues…But when I tried to deploy openvidu docker on Azure, I am getting black video screen(totally blank). Please provide a fix for this.

  1. What ports did you open?
  2. Can you show me the content of your /opt/openvidu/.env file
  3. Did you follow instructions from here?: OpenVidu Docs

I have mailed you all these details
