DNS resolution failed for tracker udp://denis.s

Hello there!

I am new to ths forum but I hope,you can help me.Since nobody else can^^

Wehen I try to seed on private Treckers, everytime this occurs:

DNS resolution failed for tracker udp://denis.stalker.h3q.com:6969/announce

Now I've been told,to get rid of this tracker,but this one doesen't appear in my tracker list:

[DHT - Verteilte Hashtabelle] nicht erlaubt 0 0 0

http://jpopsuki.eu:7531/tkm6dwxxnuoiltx9vo93z7vq3uogmlb5/announce arbeitet 8m 1s 8 0 0

This is the only tracker in my list.But I cannot seed at all. I wondermwhy that is and what I can do about this denis.stalker. I don't even know WHAT that is^^

So please help me,since I want to keep seeding^^

You can't seed on that torrent because there's no one to upload to.
