Listen server not starting on Linux?

Hello, I am currently having issues starting a listen server on my game using Unreal Engine. Into the console, I type open TestLevel?listen which does open the correct level, but does not start the listen server. I cannot connect to it from any other instance of the game. Is there something I should do to get this working on Linux, or do I have to do something extra in the editor to get listen servers to work?

Oh…
Well it looks like the world’s stupidest person missed a typo and spent a day trying to find out why listen servers weren’t working. It works fine now.
