For utorrent a lot of tracker recommend 2.2.1 but first they recommend qbittorrent which is best right now according to almost every private tracker. so if you can use qbittorrent if you dont want to and you want to use utorrent than use 2.2.1

ummmm I'm not so lucky with qbittorrent, tried using it for a while, but it doesn't go well with my internet (might be some sort of carrier thing), i changed to utorrent and even thought I'm unhappy about the ads everywhere, it works like a charm.

I'll give it a shot to other clients though.
