Sometimes it happens that some process is listening to `connector.get…

…LocalPort() + 1`, making this test fail.

Now using a non-allocated privileged port from IANA, that nobody should listen to, so the test should not fail.
It is not a 100% guarantee, but perhaps better than before, especially because now a port < 1024 is used.
