Can someone just please answer this question - online multiplayer

Thanks for the reply Dynamiquel. So after extensive research on this …farely basic issue here was my problem and solution. I wanted a dedicated server and I understand the complications of having to have a host for that server and all that but before paying for a host all I wanted was to do a simple test of using my pc as a server and conecting online with my phone to it. The issue was nobody anywere in all tutorials where mentioning the fact that the connection for UE4 servers is made ONLY on port 7777. And no matter how much I tried everything it wouldnt work cause my pc wasnt on that port.
