Project Multiplayer

Hi,

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.

Thanks,
