Sponge Pixelmon Netty stopping my server

Hi, I’m looking for help for fixing this bug that I have this days.

[04:46:48] [Netty Epoll Server IO #0/ERROR] [Sponge]: Detected broken pipe Netty error - closing channel. This: ‘net.minecraftforge.fml.common.network.handshake.NetworkDispatcher@2e61840c’ Player: ‘EntityPlayerMP[‘DanielMR9080’/3746, l=‘Survival’, x=158.03, y=78.00, z=-1236.05]’ Channel: ‘false’
[04:46:48] [Netty Epoll Server IO #0/ERROR] [FML]: NetworkDispatcher exception

We have already followed a guide with netty, but didn’t work. If someone can help me I would appreciate so much. <3
