Description of your issue, suggested solution and other information

I want to download youtube private videos from my own channel.
I am able to download the video on a local linux machine using the same command I showed above, however, I am not able to download the same video from any ec2 instance (still using the same command).

youtube-dl is latest version, python is 2.7.6 on both machines and only difference I can find out is linux kenrel version on ec2 machine is "Linux-3.13.0-128-generic-x86_64-with-Ubuntu-14.04-trusty" while on local machine it is "Linux-3.19.0-25-generic-x86_64-with-Ubuntu-14.04-trusty".

I have already asked the same question on stack overflow here, but no response yet.

I found similar issue already listed as #13822, but it is closed.

Thanks
