I have a fresh install of kubuntu jaunty 9.04 and I have set up ktorrent to operate on port 45600 and UDP on 7001. Firewall and portforwarding done as well.

ktorrent connects to some trackers without any problems but it also fails to connect to others.

I get the error: Error : Could not connect to host nyaatorrents.info: Unknown error. I get this error with any of the other trackers that I'm having problems with.

I passed the same torrent file to a friend and he was able to connect without any problems. Any ideas what is wrong?
