This monitor checks for repeated errors on requests to resolve OAuth authorization codes between AD FS Servers in a farm.
If no errors occur again within 15 minutes, the health state of this monitor will change back to a Green state and the alert associated will be closed automatically.
This error occurs when the request comes from an unauthorized user account. Only the AD FS Windows Service account has permission to resolve authorization codes.
Verify that all AD FS servers in the farm are running under the same service account. If discrepancies are found, re-join the affected nodes using AD FS Windows PowerShell cmdlets, supplying the right service account credentials.
