Blank Screen (Streaming Beyond The Local Network)

QUESTION:

Why can't I stream to a different network?  Sometimes my app says it's publishing and sometimes it crashes.  It is not showing up to the subscriber.  All I see is a blank screen.
 

ANSWER:

When you are testing on a local machine it can be difficult streaming to cellular clients, due to the fact that they need to be on the same network.  Please note, this is only a limitation of testing locally.  

  • If you deploy it on a server (AWS, Google Cloud, etc.) it will work as expected.
  • Alternatively, you can open up your local server if your ISP allows you to publicly access the IP address.  
  • You will also have to ensure that the ports are open on that network.  

We suggest deploying it to a hosting service to test mobile streaming but you could work around it.  For instance, if your Internet provider allows you to publicly broadcast the IP address you can access it that way.
