Hi Josh, thanks for the script!! I think however you might need a port number in the Splat. This works for me on Windows 2016 Server:

Write-Verbose -Message ('Use {0} as WSUS Server' -f $Name)

      $paramGetWsusServer = @{
        Name          = $Name
        PortNumber    = 8530   # 8531 is HTTPS
        ErrorAction   = 'Stop'
        WarningAction = 'Continue'
      }
