System.Net.Internals.SocketExceptionFactory+ExtendedSocketException : Connection refused 127.0.0.1:1191

This looks like a networking problem on Mac OS where it is refusing to allow listening on a loopback port.

Similar error on a different test case on OSX:

Broke CI again. https://mc.dot.net/#/user/pentp/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/3692488cefc099535d257116308f973d7cc6e263/workItem/System.Net.HttpListener.Tests/analysis/xunit/System.Net.Tests.HttpListenerRequestTests~2FUserHostName_GetProperty_ReturnsExpected

@Priya91 any idea why this specific test is getting so unlucky? Although I also see StatusDescription_SetNull_ThrowsArgumentNullException above. What is flaky about localhost on OSX and what can we do to stop it breaking CI?
