Why do I see "Your device is not authorized to enter Knox mode" when I try to unlock my container?

[Environment]
Knox Workspace

[Summary]
 
This message is displayed, because the Warranty Bit has been tripped on the device.

Your Warranty Bit may have tripped from:
  • Rooting the device.
  • Flashing a non-Samsung Certified binary on the device.
Factory resetting the device and rolling the device back to a previous version of Android will not trip the Warranty Bit.

To check if your Warranty Bit has been tripped:
  1. Turn off your device.
  2. Simultaneously press the volume down, home, and power buttons.
  3. When the Warning Screen is displayed, press the volume up button.
  4. The Warranty Bit Status is displayed in upper left hand corner of the screen.
If the Warranty Bit has been tripped, the screen will display Knox WARRANTY VOID : 0x01.

Once the Warranty Bit has been tripped, you will not be able to install Knox or access an existing Knox container. There is no way to reverse the Warranty Bit without replacing the Printed Board Assembly (PBA), a hardware component, on the device. To replace the PBA, contact your local Samsung Service Center.
IT admins can push an Attestation policy to verify when device Warranty Bits are tripped.
