Player timing out with an error when trying to connect

[daytimepanther]

Hello, a player trying to join my custom server is getting the error "Internal exception: java.netSocketTimeoutExeption: Read timed out" when trying to join the server. Other people are able to connect and he says he can connect to other servers. I was asking him a few questions on our forums and tried to figure it out but im stuck. I've noticed in the console it will print out "2013-12-21 17:07:33 [iNFO] /00.000.000.0:PORT lost connection"(It prints out an actually ip address not just zeros). I was thinking maybe it was a server problem but other people can connect with no problem? Any help would be appreciated thanks

it could just be that he is too far away from the server.

Its less likely, but he could also have the appropriate ports actually closed
