Konica Minolta Authentication Failure
Last updated September 29, 2025
Konica Minolta embedded application shows “Authentication Failure” when selecting device functions
After successfully logging into a Konica Minolta device, when I try to access ‘Device Functions’, I get an Authentication Failure message. Is there anything I can do to resolve this?

If you’re using Konica Minolta i-series devices with firmware GC2-RF, try these settings:
- Turn off the Time adjustment:
Utility > Administrator > Maintenance > Date/Time Setting > Time Adjustment Setting - Add the Web Browser button to the display:
Utility > Administrator - System Settings > Main Menu Default (Classic Style) > Not Set >Function - Enable JavaScript in the Web Browser settings:
Web Browser button > Menu > Settings > Machine Data 1 - Clear the External Application Connection:
Utility > Administrator > Network > OpenAPI Setting > OpenAPI Setting > External Application Connection:- Set to NO.
- Reboot the machine.
- Change the setting back to YES.
