Invalid Youtube url with -g

[xinobrax]

Hi,

I have a strange problem with Youtube videos in some channels. Downloading works fine, but the -g parameter results in an invalid url. Here's an example:

This works on Server A
youtube-dl https://www.youtube.com/watch?v=UhW-DenSu8A

This does NOT work on Server A
youtube-dl -g https://www.youtube.com/watch?v=UhW-DenSu8A

This works on Server B
youtube-dl https://www.youtube.com/watch?v=UhW-DenSu8A

This works on Server B
youtube-dl -g https://www.youtube.com/watch?v=UhW-DenSu8A

Every video in that channel (and some other channels) results in an invalid url. However, on an other server everything works fine. So it's kinda impossible to reproduce the problem :/ It's also not a general problem with -g on that specific server because it works fine with many other videos from different channels.

Does anyone know what causes the problem?

What do you mean by invalid URL? Downloading is only guaranteed to succeed from the same machine where you obtained the URL with -g.
