Autopilot White Glove Error 0x80070002

Hi
I need assistance to troubleshoot Autopilot White Glove Error 0x80070002 on Win10 2004. I have been searching the internet for this problem but haven't got any helpful information. Please take a look to my screenshot where I have run Michael Niehaus Script to diagnose Autopilot - point of failure is "Could not establish connectivity" and ODJ error. I have set up the Intune connector and a Domain Join Profile to all devices. Subsequently I also tried to skip AD connectivity but this is not resolving the problem.

• On my Intune Connector I found following error in event viewer: (this is repeating multiple times during enrollment)
  {"Metric":{
  "Dimensions":{
  "InstanceId":"A24408CD-28C0-4B29-B29B-0D529DBFD632",
  "DiagnosticCode":"0x00000000",
  "DiagnosticText":"Successful"
  },
  "Name":"RequestHandlingPipeline_Download_NoWork",
  "Value":0
  }
  }

What can I check?

Thank you!
