>>1506454>Error unable to download video data: HTTP Error 403There are several causes of that error for video sites that are obviously existing and working normally.
--1--
VPN blocking by some sites is classic.
--2--
The site server actively monitors user status and doesn't see that connection as being logged in to the site. Websites consider this to be bandwidth theft. The makers of YT-DLP are aware of this situation and have added a fix you can use. If you are accessing the site with firefox, see example below to make your yt-dllp look like it was the browser session doing the video request:
yt-dlp --cookies-from-browser firefox
--3--
Some sites require logged-in status to access video. So even if your web browser is logged in, the smart server at that site has security turned on and thus requires the process to be logged in. So, use this:
yt-dlp --username your_name --password your_password
