this happens on my 1.10.2 server.
I have the message from the server:

[10:14:44] [Server thread/INFO]: 10zada10 joined the game
[10:15:04] [Server thread/INFO]: 10zada10 lost connection: TranslatableComponent{key='disconnect.genericReason', args=[Internal Exception: java.io.IOException: Connection reset by peer], siblings=[], style=Style{hasParent=false, color=null, bold=null, italic=null, underlined=null, obfuscated=null, clickEvent=null, hoverEvent=null, insertion=null}}
[10:15:04] [Server thread/INFO]: 10zada10 left the game

I deleted the .dat and .json files and it works fine for the first minute, then it kicks them off. And after that when they log in it immediately kicks them off. What is strange it does not matter who the player is but the computer. I logged in with there account on the computer the server is on and it works fine, only on specific machines. It also seems that it almost always happens immediately when they are standing on water.
I do not know if it is the same issue or a different one.

This server is currently not port forwarded and is running local. The client's machine was in the same LAN if that makes a difference.
