Wierd problem when i upload a torrent...

i uploaded two torrents today yet this problem only occured with the second torrent only and not the first one.....when i uploaded the second torrent apparently some people who are trying to leech the set....cannot connect to me even though i'm connectable and my ports are working perfectly fine and im seeding just as fine i duno what up with this problem

im using utorrent.....and its kinda odd that i faced this problem with the second torrent that i uploaded and not the first

any explanation for this?

Regards.

Have you looked if the leechers are connectable? You should ask those that try to leech but can't to have a look it, most likely they will more easily see what the problem might be. I've had it that a torrent kept giving hash check fails, which is something that the uploader doesn't notice but the downloader does.
