Project Multiplayer


So i have recently packaged a version of my game to test the multiplayer, but i am confused by what i may have missed out to make each client work with each other correctly. So i have used create, join, and destroy session to make and run a client side server but if i am to test this in the engine it works perfectly but i am am to try doing this with the packaged version and a friend i have issues finding the server although i have port forwarded using the 7777 port.

Currently i am using this to search for the server

Is there a possibility that maybe i am missing something which will allow players to find each others server although they are not on the same network.

Thanks for all support,
Anymore information needed please contact me below.
