SwitchboardListener doesnt run on second machine

Development Programming & Scripting

When I run SwitchboardListener.exe on my machine it runs without a hitch. I have pulled it from the engine binaries and grabbed all the required binaries for it to run and packaged it seperatley to be deployed onto listener machines. When I unzip it onto those secondary machines, it will not run. I am running it as headless through gitbash with the following command
./SwitchboardListener.exe -NullRHI -nosound -port=(uniqueport#)
On the secondary machines, it runs to the point of LogSwitchboard: Display: Initialized but NOT LogSwitchboard: Display: Started Listening, so it cannot connect to my main Switchboard instance. I have tried:
Restarting pc
Trying unique ports
Running as admin
Running on 3 different machines
Running with machine specific IP through the -ip= cmd line arg

Any thoughts are greatly welcome, I’ve been stuck on this for over a day ATP…

So, running it on a 4th machine didnt work, but running it on a 5th machine which DOES have Unreal Engine installed (the previous 4 didnt) allowed it to work. However, installing unreal engine on all the listening machines isnt possible…

Figured this out, when SwitchboardListener is first run, it prompts you for a password. It saves this password to the Windows Credentials Manager under ‘Windows Credentials’. It creates 4 credentials, copying these credentials over to the machine you want to host SwitchboardListener on fixed this issue. Ensure the passwords are set as the same one as the computer you grabbed SwitchboardListener from.
