Unable to update help in MS PowerShell

Hi MargaretSpace24

Based on the error message it looks like a network issue. Are you going through a proxy or firewall? It could be that they are not allowing all IP addresses for the Microsoft download center. If you are trying to understand which IPs to allow it is here. https://www.microsoft.com/en-us/download/details.aspx?id=53602

Hopefully this will resolve your issue.
