I have a problem with youtube-dl library (https://rg3.github.io/youtube-dl/). I use youtube-dl not for directly downloading videos by this library, instead I first generate link using command like this:
youtube-dl --simulate --dump-json --prefer-ffmpeg -- -CmadmM5cOk
I get needed format link from json answer, I use default format 1280x720 mp4. Links look like this "https://r4---sn-nto52nx-px8e.googlevideo.com/videoplayback?lmt=1432339993780507&ip=x.x.x.x&key=yt6&fexp=9408710%2C9409069%2C9413137%2C9415365%2C9415485%2C9416023%2C9416126%2C941...".
Then I use this link to download video from different PC in different locations. For most links it works ok, but there are some videos, for example https://www.youtube.com/watch?v=-CmadmM5cOk, that I can't download from different server or PC, it returns ERROR 403: Forbidden.
So what I tried so far, I have 2 server and my local PC, all 3 of them are located in different countries, USA, England and Ukraine.
For example, I run youtube-dl and get link on Server 1 in the USA, I get link, I can it download in this Sever 1, but on Server 2 in London and my local PC in Ukraine it returns ERROR 403: Forbidden.
Another example, I generate link on Server 2 in London, I get different link, I can download it on the same server, but when I try on Server 1 or my local PC I get the same ERROR 403: Forbidden. The same when I generate link on local PC and try on servers.
This happens only with only some exact videos, but there are a lot of them. Some of videos that returns 403: https://www.youtube.com/watch?v=09R8_2nJtjg, https://www.youtube.com/watch?v=7PCkvCPvDXk.
Thank you, I appreciate any help!
Update:
I'm trying to use suggested by you option "-o -" to output video file to stdout and then I retranslate it to user. But I have another problem, it works if I login with ssh and try command with my user, but it throws 403 error when I launch the same command under "www-data" user. Here is verbose output:

UPD:
To get rid of 403 remove the cache by running youtube-dl --rm-cache-dir on behalf of www-data.
