Failed to open descriptor, when trying to start game in multiplayer.

I tried everything, to no avail, no matter what i do it always fails with the same “Failed to open descriptor”

this is by bat for starting server

“G:\u\Epic Games\4.10\Engine\Binaries\Win64\UE4Editor.exe” F:\Worlds\WorldsUE410\Worldsue410\Worldsue410.uproject ProjectName init?Listen -game

all paths and names are correct, what is wrong?
