@Rayshine In qBittorrent, switch to the "Trackers" tab (1) and check what it says at (2). If it says "unregistered torrent", it has likely been deleted. I'm fairly sure it has because I just got sent to a 404 page by the link you gave.

Follow the line back from "Unregistered torrent", to the "Status" column. Is that "Not working"?
This status / message is usually the result of a torrent having been deleted. That could be because of copyright strikes, site rule infringement, or simply if a new torrent isn't seeded to completion. (i.e. At least one person has downloaded it in full.)
As long as the torrent isn't huge, and it's not obscure enough that few want to grab it, it should download for someone pretty quickly, depending on your own upload speed limit. If in doubt, set it going on a Friday evening, so it has all weekend to complete.
Once you've created and uploaded it, you MUST download the torrent from the site, as if you were just grabbing any other torrent, and use that one, NOT the one you created. Once you've done that, check in "My Torrents" that "Visible" becomes "Yes". It will only do so after you've 'force rechecked' (pretended to download) your own torrent.
If at all in doubt, or you get stuck, check out the guide at https://www.gaytor.rent/uploadguide.php Go through it carefully to make sure you don't skip any of the steps.
