Private trackers - Unable to connect

[Eterno]

Hi,

I've been a PC user since...ever, and I just bought an Imac.
Everything's new and fun but I have one annoying problem with my torrents and I can't find the solution.

FYI I tested Transmission, Utorrent and Vuze. They all gave me the same mistake. I am now only using Utorrent.

Problem is: I cannot download from any of my private trackers. Public trackers are no problem, I download full speed and port are open.
Private trackers give me the red arrow and tracker says: connection closed by peer.

Since all the software give the same error I guess I need to change something in my mac settings but I have no idea what.
Everythings works fine on my PC so it has nothing to do with my ISP.

Anyone can help?

I found the cause of the problem.
The only difference was my PC was connected by Ethernet and Imac by Wifi.
I tried to connect my Imac by Ethernet and it worked like a charm.

I guess my wifi is not private tracker friendly. I'll try and find out why.

Sorry for this useless post.
