does he lose the connection immediately or after a couple of minutes (or later?)
how many players are online at your server when this is going to happen?
[TcpProtocolDecoder ExceptionCaught] /50.80.59.94:52077: java.io.IOException: An existing connection was forcibly closed by the remote host
[TcpSessionHandler ChannelInactive] /50.80.59.94:52077
This is the code just before he starts getting the lost connection warning. It only affects him and it is usually within 5 to 7 minutes
The number of players varies from 3 to 5
then he times out.
