Common issues and Troubleshooting

Unreal is open and playing, but appears red in studio

While trying to control a scene via Studio, you follow the steps for going on air and everything seems fine, but the monitor at the bottom of Studio main interface that relates to Unreal engine (or other rendering engines) out channel is red.

First you should check that Unreal is working on the correct project and in play mode.
If everything is as it should be, and the Unreal channel monitor is still red, that might be because the render machine does not have Erizos Agent installed and running.

Summary

Make sure the Render machine have Erizos Agent installed and running.
