Thank you for replying. I found the issue. I changed the play list order in play.html.
playOrder = ["webrtc", "hls"];
to
playOrder = ["hls", "webrtc"];
I did this because I want it to play via hls rather than webrtc. But that change caused the issue. Is there some other way to have it default to hls rather than webrtc? I made this same change in 2.2.1 so I didn't expect this to cause a problem.
