Solved Local Server

[Tyhawk master]

okay so me and my friend is making a Local server (Same House) and i host the server on my Computer but she can not log into the server. (We are using the Default ip 127.0.0.1) it lets her Log into the account (i have made it Account 1, Password 1) but when she tries logging onto the actual world she gets a error saying the server is offline. But i can still get on the server. How do i fix this so that we both can get on the server.
P.S i have made her try the IPV4 adress and the Default gateway. Still both not working

Solved in teamviewer, he used his IPv4 address in config.lua and in both IP Changers.
