Hi, @PeterRaban
Thank you for posting in Microsoft Q&A forum.
The issue might occur in either of the following situations:
- The service connection point is running in Offline mode.
- The service connection point is running in Online mode, but it can't obtain the Admin UI content payload.
If the service connection point is running in Offline mode, use the service connection tool to download and import updates that include the Admin UI content payload.
If the service connection point is running in Online mode, review DmpDownloader.log for failures that occur when accessing the payload URL.
