Description

Downloads from this source used to work and now don't anymore. The URL itself has changed slightly since my last visit about one week ago. I'm sorry, but I can't add much of interest because the page is programmed in JavaScript.

As a workaround you can pick the URL to the m3u8-file hosted at akamai from your browsers developement console or "Network Monitor" and hand that to youtube-dl. That still works.

I think #28549 is a duplicate of this issue?
