Why is my Torrent Not Working?

When your torrent doesn’t work, there can be two problems. Firstly, the site would have glitches.

The ISP cannot block the software itself, so it often blocks some communication channels to prevent you from accessing the software. The second reason is the most common one.

No, it doesn’t. However, it makes it extremely hard for them to track your internet activity. You can switch to Cloudflare, Google DNS, or anything that works best. Since the level of security offered by these DNS services is of high level, ISPs will have to spend a lot more to crack.
