Description

Seems like support for InfoQ is currently broken. I took that URL from the InfoQ tests (BTW, where do these run?). I see the same behavior with https and with a different video. Thanks for your help!

InfoQ's CloudFront now needs Referer and Cookie to be set correctly to access video streams

And AFAIU it's setting it's Cookie with a fair bit of JS
