it says that they are not online because it sends them a query packet (like getinfo for the quake3 based games) and it receives no reply so the servers are offline or you have inserted a wrong IP and/or port.
if you remove the -i option it will not request these informations, maybe set also the -t option depending by the game:
Code:
-t TYPE select the type of rcon, the following TYPEs are supported:
0 = Quake 3 engine 1 = Medal of Honor 2 = Half-Life
3 = Doom 3 engine 4 = Quake 2 engine 5 = Project IGI 2
