The active torrent trackers that is active and actually worth announcing to is ever changing.
If you want to find extra seeders or peers for a torrent you’ve uploaded or if you have a stuck torrent, then try the following.

Click on the torrent in your client. I’m using qBitTorrent so the procedure might now be exactly the same for you….
Then click on the tab named “Trackers”. Right click in the box of trackers and click on “Add trackers” or whatever it’s called. And add the following trackers:
