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.
