Listen Error on Leaseweb Seedbox

I'm receiving a red icon Listen Error in uTorrent on my Leaseweb seedbox. I tried all the ports they offered me, 21, 80, etc. but they all won't change that icon to a green ok status. For anyone who's used Leaseweb, has this happened to you before and how can I fix this? Since I am administering this remotely my options are a bit limited.

Thanks

Thanks, but I have already tried to disable that and it still gives the red icon error in uTorrent. Is this a normal problem though for Leaseweb seedboxes? This is the first time I've used them.

Had the same problem. Found out that the port I was using already was being used by a other program.
Just add some random port to the tcp/ip filtering, and get utorrent to use that. it should work.
It did for me. :)
