Im trying to make a 1v1 multiplayer game. I am trying to make the player to either join or create a room. Can this be done with just blueprints? Also maybe the room maker becomes the host of the server due to my slow and limited bandwidth.
Thanks for the help!
This is possible, I am doing a 2 player coop game. And I have tested it out with a friend using steam.
It shows what nodes to use and how to setup the menus and button for host and join.
follow every step and you will succeed… hopefully 
Remember to enable steam plugin on unreal editor.
