Hello,
I can not claim my server http://www.gametracker.com/server_info/216.52.143.110:25565/ as it has the wrong query port listed. The correct port is 25565. When I added it I was unsure of the query port and put the wrong one. I believe Minecraft servers default to this port now since they have built in query, and you should really change the recommended/default setting.
Thanks, Nickinpie
