0 HEALTH

Recently my BitComet doesnt work , its 0.71 . it shows Seed/Peer (all) 0/0[0/1428] but the health is 0% -_- help plz , is it something to do with my firewall . its works before

A health rating of zero means that nobody in the swarm has any part of the file. THey’re all leechers, with 0% downloaded, and there are no seeders at all. So unless someone starts seeding in the future, this torrent isn’t ever going anywhere.

Try switching back to 0.70 or get µTorrent and compare.
