Cause
Imunify360 license can be used on one installation at a time.
The error may appear due to one of the following reasons:
-
More than one Imunify360 is activated with the Imunify360 license
-
Imunify360 has been reinstalled on the same Plesk server, thus the same server to be registered twice
- Imunify360 was installed on the newly migrated server with the old server's IP address
Resolution
If the old server where Imunify360 is activated with the mentioned <KeyNumber> is still online, run the following command to unregister Imunify360:
# imunify360-agent unregister
If the old server is offline, contact CloudLinux Support for further assistance.
