My internet connection is stable albeit slow, I can download and seed torrents on other sites so I don't think my ISP blocks that, I just seem to have problems with this site in particular. People can download stuff from me but download doesn't start on any torrent, even freeleech ones.

Thanks for your answer, I hope I find a way out of this, it's very frustrating

Torrent not downloading can be caused by the network restriction.
If you're on a public network, such as school network, company network, coffee shop network, etc.,
it could be that the network you're using is blocking torrent files.
Or it could be your ISP blocking torrenting traffic to prevent network congestion.

If you are using VPN [try to disable/check settings] and re-start your client ...

Check your firewall settings ...
From the Start menu, click Control Panel, then click System and Security.
Under Windows Firewall, select either Check firewall status to determine whether the firewall is turned on or off,
or Allow a program through Windows Firewall to allow a blocked program through the firewall.

Tried to change torrent client but it did not work.

Paid seedpoints to have a good ratio, still does not work for freeleech or regular torrents.

No idea what's wrong.

When I click on a torrent it's "stalled" and the tracker "does not work".
