Hi, i updated my server, and since i reopened it, in gametracker appears offline, I checked the query and the port and are the same in config, firewall and gametracker (Port:25565,Query:25560). I tested the query with a webtool and work fine.

Thanks.

The following will help you:

1. Your server should be up-to-date
2. You should not have any query plugins
3. Nothing on the server should be blocking GameTracker from scanning on the query port (Firewall, router, etc)
4. You should have query properly setup http://www.gametracker.com/games/minecraft/forum.php?thread=58741

Certain additional plugins like MCPC+ have been known to cause issues with the server's query protocol.

Minecraft servers would the best if the join and query port are the same.

I've tested scanning your server from various sources and confirmed GameTracker is not alone in being unable to scan it.
