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

Are there any workarounds or quick fixes for this?

Fix for this issue will be incorporated in the next version of youtube-dl. Thanks for the report.

I believe this issue to be fixed in youtube-dl 2015.01.05 or newer. See our FAQ if you need help updating.

@joecrayne I can't watch the video on a browser: This video has been removed by the user(which is also the message I get with youtube-dl).
