New to this need a little help on multiplayer pls

Hello all
I recently started trying to make a game in unreal i have managed to get a multiplayer setup using steam working however im running into a problem that i cant seem to understand my self maybe you can? When i click play game it creates a server and then put you in the level(what it should do). however doing this will display the loading screen, shows the level to load for a split secon and then kick you back to the main menu and then not display the main menu widget i have made. I check the log file and found a few errors but i got no idea what they mean here are the one that i can see.
