404 Error on XHR GET Request

Unable to replicate.

The only 404 I get is to the m3u8 playlist, which is expected for a offline channel

Sample code:

https://twitch.extensions.barrycarlyon.co.uk/temp/player_test.html

Time of writing the channel is offline.

I bound a video_play and got a video play as the stream went live

So I suppose what are you seeing 404?
