Stalled status...

[qbitjoe]

I'm trying to download some torrents found via qbittorrent search engine...
Those files seems to have a good seeds and peers number, so I've added to my download queue.
But they rest indefenitely in "stalled status".

I've noticed that all theese torrent are not shared via one or more trackers, they instead are just distribuited via DHT, peer exchange, and LSD (I don't know this last one method).

For an added torrent I can see some good peers with a 90 and more percend completed download, but no one ups to me.. And I rest in stalled status...
I'm downloading an other torrent published also on a tracker and it was started in few seconds without any troubles. So I think there could be a not so good dht management or something similar. Or torrents I've chosen are not so good.
What could be the matter?

LSD local seed discovery. In the options menu you can find as a local peer discovery.

That option is yet enabled...
