Frequently Asked Questions

Why do I see a blank screen during local testing?


During a local test, upon publishing, sometimes my app says it is publishing and sometimes it crashes.  It is not showing up to the subscriber.  All I see is a blank screen.


Please make sure that you are running all your devices on the same network (using the same IP address or host).  If using mobile devices, make sure the IP address is from your wireless connection.

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.
