Cause

The root cause of the authentication error was a configuration issue related to the Azure app's certificate. The error message indicates that the certificate with the specified thumbprint is not registered on the application. This prevents the authentication process from being completed successfully.

 

Resolution

To resolve the authentication error in the Merge1 portal, follow these steps:

  1. Visit the Azure Portal or use MS Graph to access the configured keys for the Azure app with the ID  'ABCDEFGHIJKLMNOPQRSTUVXYZ123456'.

  2. Delete the old certificate from the Azure certificate list.

  3. Update the Azure app's configuration in the application registration portal with the correct certificate information.
     
  4. Retry the authentication process in the Merge1 portal.
