AZF9135E RADIUS error after challenge response; soft-deny and no PWFALLBACK


    Explanation
      A challenge response credential request sent to the RADIUS server did not get a response
        and timed out. This error is generated only if a timeout or error is encountered after at
        least one valid packet is received from the RADIUS server.  The user receives an
        authentication failure.

    

    User response
      Retry authentication from the beginning.
