Description
This article describes how to recover the FortiGate from not being able to delete the central-management setting because of a GUI message:
'Please unregister device from FortiManager first' (GUI).
'Please unregister-device from FortiManager first. object set operator error, -582 discard the setting Command fail. Return code -582' (CLI).
Solution
Investigating this problem. In the meantime this should serve well though:
- From GUI add 0.0.0.0 as FortiManager IP.
- it will logged out from the FortiGate.
- Log in again.
- Now it will be possible to set central management to 'None' without unregistering.
- Apply the changes.
