Show what process is already running on the requested port

[mmaslowskicc]

The AlreadyRunning exception names the requested process and port (which we probably also know from the traceback), but not the service that is running on that port. This usually needs to be debugged in different ways depending on the same service or a different one being already running.

https://pythonhosted.org/psutil/#psutil.net_connections should provide the needed info.
