PowerCLI: The SSL connection could not be established, see inner exception.




Summary:
Unable to connect to ESXi/vCenter server with Connect-VIserver cmdlet, get the following error:
"The SSL connection could not be established, see inner exception."

Be sure to "Set-PowerCLIConfiguration -InvalidCertificateAction:Ignore" if you plan to connect to an ESXi/vCenter that does not have trusted certificate.  Interestingly, something must've changed recently because the PowerCLI module actually would output a more descriptive message about setting your PowerCLIConfiguration.

This appears to be the case w/ Powershell Core 6.1.  I'm actually unsure when this behavior started happening and whether is module or powershell related.  Regardless, figured I'd post this since I was initially confused myself when running some things on another system.
