Plutonium

I recently followed the guide to host a zombies server on my computer and that was successful. However, I noticed that Plutonium would no longer launch zombies while I was running the server. Launching Plutonium works, but when I click the play button the cmd window pops up for a second before disappearing and not launching the game.
So far I've tried to launch the game first and then starting the server, but in that case, the server does not work and I can't find it on the list. In this scenario the game works fine though. I've also tried to run the game with files in a different location than the server, but that yields the same error.
Not sure if this is allowed but my video was too big and couldn't upload so I put it on imgur. https://imgur.com/a/YkhEUuI

Dss0 Looks like using port 4977 on the server and launching the game first solved the issue. Thanks for the assistance!
