Port 443 is already in use ( code: 'EACCES', errno: -4092,)

Heya,

You're already running something on that port, be it an application, a server, whatever it may be.

It could also just be a second running instance of server.exe.

Don't do that.

Browse around in users/

There should be an option that allows you to change the IP:port

Keep the IP, change the port

Don't forget to apply the updated settings to launcher settings too
