The error message indicates that the script failed to authenticate to the remote server using CredSSP. CredSSP is a security mechanism that allows a client to delegate its credentials to a remote server for authentication. To use CredSSP, both the client and the server need to enable it and configure the role and the trusted hosts. The command Enable-WSManCredSSP -Role Client enables CredSSP on the client side and specifies the remote server as a trusted host. This command should be added to the script before invoking the Invoke-Command cmdlet that runs the script block on the remote server. The other commands are either irrelevant or incorrect for this scenario. References: Nutanix Calm: PowerShell Scripts - Read the Docs and Enable-WSManCredSSP (Microsoft.PowerShell.Management) - PowerShell | Microsoft Docs.
