Hi, My server has 135 slots.

But when he reach the 130 players, he stop showing the players in game tracker like

if has 128:135 it shows in gametracker the players..

But when it has 132/135 he stop showing players like it stays:
0/135 but the server is online and with players....

I am afraid that when he is 0/135 and has players that i will lose rank..

Someone can help me?

Other users have experienced that as well. The Minecraft server stops reporting players after it hits a number, somewhere around 130 players. We do not know of any conditions that would affected, as you can see some servers seem to work just fine. However, until Minecraft resolves it will be a problem with tracking some servers.

so...the rank will not count right?

Unfortunately yes. When your server shows at 0/135, GT is essentially seeing it as empty.
