Was trying to grab The Witcher 3 trailer when I got this error. Tried other videos and they worked fine. This one consistently doesn't work though. However I can download the video with the Youtube Center Greasemonkey script.

As it says in the error message, update to the latest version and see if that works. youtube-dl -U

Yeah I'm stupid. Though youtube-dl -U never works for me on Windows so I have to download it manually.

It seems YouTube does not include STS parameter in the webpage anymore. So it is missing always and for age gated videos with ciphered signatures you will get response 403: Forbidden.
Here is an example video: http://www.youtube.com/watch?v=07FYdnEawAQ

I'm closing the issue, it works in the last version.
@martinswacke, see #4108.
