How to Run Dedicated Server Games From Commandline


Dear Community,

I"ve just created a tutorial on how to run Dedicated Servers with 2 connecting clients from commandline! (editor closed)

The key part is that you can’t use for the clients who want to connect to the dedicated server.

#Dedicated Commandline

When the server instands loads via this commandline (Assuming bat file is in same dir as .uproject of your game)


"C:\Program Files\Epic Games\4.9\Engine\Binaries\Win64\UE4Editor.exe" "%CD%\YourProject.uproject" MapName -server -log -nosteam

You then have to check the log to find out what the IP address for the server is listed as!

You’ll see something like this:

#Client Commandline

You should use that IP address for your client commandline:


 "C:\Program Files\Epic Games\4.9\Engine\Binaries\Win64\UE4Editor.exe" "%CD%\YourProject.uproject" -game -ResX=800 -ResY=900 -WinX=800 -WinY=20 -log -nosteam

#Running Dedicated w/ 2 Clients

#For The Community

There was no tutorial I could find that explained this so I wrote this for your enjoyment.

Have fun today!



#Why Do Clients Load Into Black Map?

Project Settings-> Maps and Modes → Show All Advanced

Server map was probably “Entry”

Yeah, that sounds about right coming from you Rama. Good job!

Hey Rama, Good Job. I’m just wondering if you would happen to know how to -log a dedicated server that was launched through FPlatform::CreateProc. I am able to see the server launch in my processes and I see the map opening correctly. I dont however see where to add the -log switch commandline argument so I can debug those Servers

Thanks for your time!
