youtube-dl is unable to download videos from private twitter accounts. I can't provide a twitter account, but you can easily reproduce the same issue by trying to download any video from any private twitter account you follow. I put all twitter.com cookies in cookies.txt(which includes so-called the "guest token"), but that did not help.
