I'm using Azure GovCloud and Azure Automation.
I can upload and compile simple DSC Configurations.
I can add Azure VMs as DSC Nodes.
However, DSC Nodes report failures on every run but the first.
Under Reports, Consistency is in Failed state: "Checksum for configuration does not match."
Am I supposed to do something about Checksums while using Azure Automation?
How can I further debug this?

Clint and I are both trying Azure Automation, USGov, but using different servers in different resource groups with different configurations. Similar results:
PS C:\Users\pburkholder> Update-DscConfiguration -Wait -Verbose -Debug VERBOSE: Perform operation 'Invoke CimMethod' with following parameters, ''methodName' = PerformRequiredConfigurationChecks,'className' = MSFT_DSCLocalConfigurationManager,'namespaceName' = root/Microsoft/Windows/DesiredStateConfiguration'. VERBOSE: An LCM method call arrived from computer MYVM1 with user sid S-1-5-21-203942804-2365848562-3944707112-500. VERBOSE: [MYVM1]:  Executing Get-Action with configuration (null)'s checksum: . VERBOSE: [MYVM1]:  Executing Get-Action with configuration 's checksum returned result status: GetConfiguration. VERBOSE: [MYVM1]:  Checksum is different. LCM will execute GetConfiguration to pull configuration . VERBOSE: [MYVM1]:  Executing GetConfiguration failed. Configuration is not pulled.

VERBOSE: Time taken for configuration job to complete is 3.735 seconds
It looks to us like the target is telling the AzAutomation that it has a null configuration, then the LCM will run `GetConfiguration`, which makes sense. Except `Executing GetConfiguration failed. Configuration is not pulled.`
We're following the steps at https://docs.microsoft.com/en-us/azure/automation/automation-dsc-getting-started.

Update: It works as advertised in public cloud. Opening support ticket for USGov....
