title: Application Error while deploying flask app to Azure
body: <p>I am trying to deploy flask based app to Azure. The app is working fine locally but I get Application error on Azure.</p>
  <p>I checked the docker logs and found that container does'nt respond to the port.
  I have tried changing port by configuring WEBSITE_PORT, still same issue.
