I ended up installing it and just gave the galaxy when prompted a different name, and then went back and manually edited the config as I wasn't sure if it was going to try and auto-start and mess things up.
But it starts up beautifully! However when I do a /manager stop it's not stopping the server, there's a counter that goes up and when it gets to 30 I cancel that, attach to console and do a manual /stop. No players connected.
Additionally cannot get the web component to connect. Ports are opened and I've installed under Apache and no-go. Tried to start the PHP Web and that fails to start.
Happy to jump on a Discord with you and work through my quirk of setup to figure it out as needed.
