Funny enough, the site is reporting port 3000 to be running a web server. It is not - according do nmap and my knowledge.

Any ideas on this?

If you're on Linux, BSD and macOS, you can run:

    sudo lsof -i | grep 3000
To try and see if a process has claimed the port.

On Windows:

    netstat -ab
I've forgotten so much Windows I don't know how to filter the result, but it'll give you a list of ports and processes.

Some BSD systems won't have lsof out of the box, in which case fstat/netstat will give you the results you want.
