By setting 
    LocalAddr => 'localhost',

on the $server_socket in the server code, you are limiting it to listening only on the local loopback address.

Delete that line, or set the LocalAddr to "0.0.0.0" , which allows binding to ANY available local IP address.

This will enable connections from outside the local 127.0.0.0 network to connect.
