Registration of the Dsc Agent with the server failed


Setting up the DSC pull server and the node for the first time and I am hitting an error that I couldn’t solve. Please help.

Server configuration

Server in Azure

        [string] $certificateThumbPrint,

        [Parameter(HelpMessage='This should be a string with enough entropy (randomness) to protect the registration of clients to the pull server.  We will use new GUID by default.')]
        [string] $RegistrationKey   # A guid that clients use to initiate conversation with pull server

Created the metamof using this configuration

configuration PullClientConfigNames
    Node localhost

            RefreshFrequencyMins = 30
            ConfigurationMode = 'ApplyAndAutoCorrect'

            ConfigurationNames = @('testconfig')

When running the command

Set-DscLocalConfigurationManager -Path .\PullClientConfigNames -Verbose

Getting the below error message
