You’ll need to compile the engine source to make a dedicated server.
Let’s try to keep discussions constructive. It can be frustrating how much space compiling Unreal needs and how long it takes, we would love for it to take less time and disk space. But taking it out on our staff and the EDC community who are here in the forums with the goal of helping people is not behavior that I tolerate.
We make this clear in our Community Guidelines.
