Netstat does not show anything listening on the port.

On my Windows 10 2004,

netsh interface ipv4 show excludedportrange protocol=tcp

includes this line in its output:

Protocol tcp Port Exclusion Ranges

Start Port    End Port
----------    --------
      6953        7052

I'm not sure what those entries are for or whether they are the same on all PCs...

Ideally, a different port should be used if the error is encountered.

It seems like the code runs the portscanner module to check for a port that does not have something listening, however, this fails to detect the excluded port ranges, since they are reserved for some reason, without something listening on it.
