fyi, the trackers of openbittorrent and tpb are dead and buried.
udp at publicbt doesn't work as well.
and not only since yesterday . .
downloading your torrent "as is" leaves one with no connection.
adding a valid tracker isn't a big deal for seasoned torrenteers.
"average users" however, may find themselves stumped and helpless.
you might want to adjust your settings.
