I am writing a software for downloading videos from a website. I found a direct link (https://video.sibnet.ru/v/24b1b8b0733c192f76dc6e32bafbd109/4108163.mp4) to download video through HTML markup on the site (https://animejoy.ru/tv-serialy/2341-zakazyvali-krolika-3-sezon.html). When I click the link, the server returns 403 Forbidden. Why can I watch the video through the player on the site, but can’t access it directly?
