Minecraft LAN will not work for me and my friend it joins the world and then kicks us after it not loading., we have tried many things including different java versions, different game versions, firewall off on both computer and both routers. We have also followed the battlefront guide which tells us to set the metric to one which also did not work.

The error we get is
internal exception java.io.ioexception an existing connection was forcibly closed by the remote host.
We can play on LAN on two other games though which include Wolfenstein Enemy territory and Xonotic
If you can help please let us know how to fix this issue.
