Hello,

I would make sure that you have TCP port 1935 open in your firewall of your Wowza Streaming Engine system. If the Android device is on a separate network than the Windows 10 station, you will need to setup port forwarding and use the Public IP address for your connection.

Also here’s a [GoCoder Android article](https://www.wowza.com/docs/how-to-use-wowza-gocoder-video-broadcasting-android-app) that has setup and troubleshooting tips.

Regards,
