Fix PowerShell Error: “The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.”

Just as a reminder.

When getting this error:

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

…just add this to your PowerShell script:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
