Can anyone help me?

Okay, so yesterday (Indonesian time) is when this all started, I join Redstoner and after like 10 seconds, it disconnects me from Redstoner, and this only applies to redstoner.

I checked by going onto that one server everyone talks about at redstoner, and boom, it still works. So I dont know about you guys but I think there is something wrong in the connection between me and redstoner.
