Not sure whats going on. I mean if you look at the weekly stats it shows my server as having players for those days. However, my server is shown on your site to be offline. I don't understand how that's possible.

Did you recently make any changes to the server? Or add any plugins? It doesn't seem to be responding with the correct query protocol anymore.

My server is running:

>version
19:53:01 [INFO] This server is running CraftBukkit version git-MCPC-Plus-575dff4
(MC: 1.4.7) (Implementing API version 1.4.7-R1.1-SNAPSHOT)

Which is a Tekkit Lite mod.

It has these plugins:

>plugins
19:51:59 [INFO] Plugins (10): OpenInv, bPermissions, PlugMan, WorldEdit, WorldGu
ard, BanItem, Essentials, EssentialsChat, EssentialsSpawn, VanishNoPacket
>

Settings:

server-ip=74.91.113.50
server-port=25565

enable-query=true
query.port=25566

rcon.port=25575
rcon.password=MYPASS

motd=DISC-FF is le best <3
server-name=DISC-FF's Tekkit Server\!


I know this can't be a Firewall issue as it has worked in the past on this site.

MCPC+ has been problematic in the past for admins who use it. You'll likely need to avoid it (or update) if you'd like the server to scan.
