[Net.SecurityProtocolType]::Tls13 Throws Error on Unsupported Systems

[thigley986]

The line [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12, [Net.SecurityProtocolType]::Tls13 throws an error on systems that do not support TLS 1.3.

I suggest checking first to see if the system supports TLS 1.3 and, if not, only invoking:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Which version of PowerShell are you using? It works for me on PS7, but I'm going to correct this anyway.

Powershell 5.1, Build 17763, Rev 1490 on Server 2019.

Thank you for the bug report. I've fixed this by enabling TLS 1.2, then checking to see if TLS 1.3 is available before attempting to enable that. I should have the new version up on the PowerShell Gallery soon.
