Hello,

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

```
configuration Sample_xDscWebServiceRegistration
{
    param
    (
        [string[]]$NodeName = 'localhost',

        [ValidateNotNullOrEmpty()]
        [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.')]
        [ValidateNotNullOrEmpty()]
        [string] $RegistrationKey # A guid that clients use to initiate conversation with pull server
    )

    Import-DSCResource -ModuleName PSDesiredStateConfiguration
    Import-DSCResource -ModuleName xPSDesiredStateConfiguration

    Node $NodeName
    {
        WindowsFeature DSCServiceFeature
        {
            Ensure = "Present"
            Name = "DSC-Service"
        }

        xDscWebService PSDSCPullServer
        {
            Ensure = "Present"
            EndpointName = "PSDSCPullServer"
            Port = 443
            PhysicalPath = "$env:SystemDrive\inetpub\PSDSCPullServer"
            CertificateThumbPrint = $certificateThumbPrint
            ModulePath = "$env:PROGRAMFILES\WindowsPowerShell\DscService\Modules"
            ConfigurationPath = "$env:PROGRAMFILES\WindowsPowerShell\DscService\Configuration"
            State = "Started"
            DependsOn = "[WindowsFeature]DSCServiceFeature"
            RegistrationKeyPath = "$env:PROGRAMFILES\WindowsPowerShell\DscService"
            AcceptSelfSignedCertificates = $true
            UseSecurityBestPractices = $true
            Enable32BitAppOnWin64 = $false
        }

        File RegistrationKeyFile
        {
            Ensure = 'Present'
            Type = 'File'
            DestinationPath = "$env:ProgramFiles\WindowsPowerShell\DscService\RegistrationKeys.txt"
            Contents = $RegistrationKey
        }
    }
}
```

PS C:\Program Files\WindowsPowerShell\DscService\Configuration\> Get-DscConfigurationStatus

Also created the testconfig.mof and the corresponding .checksum under the DSCService\Configurations folder

**Client configuration**

Test client machine - local desktop

Created the metamof using this configuration

```
[DSCLocalConfigurationManager()]
configuration PullClientConfigNames
{
    Node localhost
    {
        Settings
        {
            RefreshMode = 'Pull'
            RefreshFrequencyMins = 30
            ConfigurationMode = 'ApplyAndAutoCorrect'
            RebootNodeIfNeeded = $true
        }
        ConfigurationRepositoryWeb dsc-test
        {
            ServerURL = 'https://dsc-test.preprod.com/PSDSCPullServer.svc/'
            AllowUnsecureConnection = $true
            RegistrationKey = 'fc2a988a-aacf-4c6e-a388-fdd0c42338a8'
            ConfigurationNames = @('testconfig')
        }
    }
}
PullClientConfigNames
```

When running the command

Set-DscLocalConfigurationManager -Path .\PullClientConfigNames -Verbose

Getting the below error message
