The current list of trackers used on the magnet links is out of date.

First, drop this ;
udp://coppersurfer.tk:6969/announce

udp://tracker.zer0day.to:1337/announce
udp://opentracker.i2p.rocks:6969/announce
udp://tracker.leechers-paradise.org:6969/announce

Switch them for these which have been stable for a while ;
