This is expected with Windows 10 versions prior to the 2019 releases. If you can update to the latest supported versions of Windows, you will get a newer Powershell, and won’t likely see this. Older versions of PowerShell are not configured to allow the use of TLS 1.1 and 1.2.
There’s an additional command you can run to prepare older versions.
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls12
That command can be modified to remove TLS 1.1 if your network has blocked that version too.
