Valid/invalid googlevideo.com URLs

[jonathanasquier]

Hi,
I have 2 identical VMs (Ubuntu 14.04, same config, mapped ports, everything) with 2 identical latest youtube-dl version
I do :

 youtube-dl https://youtu.be/YOUTUBE_ID --get-url -f best

Works well on one (on my local dev machine too), 403 forbidden on the other one. (Same behaviour with other youtube-dl versions)

Am I missing something? Could something prevent the other identical VM to work properly?

Thanks a lot!

The urls you get with youtube-dl are only guaranteed to work from the same IP and with the same cookies. Please explain how you try to download the videos, does youtube-dl URL -f best correctly download the video?

Interessing, on the failing VM youtube-dl URL -f best downloads the video properly, and wgeting the URL works the same way.
But requesting the URL on another IP always fails when generated from the 1st VM, and always work when generated from the 2nd VM... (I have an API/client app architecture, my VMs are production and pre-production)

Sorcery? :P

As already mentioned by @jaimeMF final download URLs are not guaranteed to work on another machine/IP apart from where it has been extracted. More on this.

Okay... just thought is was strange it had a different behaviour with the same URL... I believe I'm gonna have to deal with it!

In addition, you can probably track these URLs with this approach to apply different scenario for them.

Interesting, gcr=ie in the "failing" urls gcr=us in "working" urls, matches the VM's IP country obviously, but still no work around for me right now :) thanks!
