Updatable objects appear as 'no longer supported'

 

Symptoms

• In some scenarios, the following validation warning appears on an updatable object: "Object is no longer supported. Enforcing security for this object is not possible." However, the object is still available in the updatable objects picker.

Solution

Updatable objects use CloudGuard infrastructure. To resolve this issue:

1. Restart the CloudGuard controller by running these commands on the Security Management Server:

   • cloudguard stop

   • cloudguard start

2. Open the updatable objects pane

Notes:

• If you are using Smart-1 Cloud Contact Check Point Support to solve the issue.
• If you are using Multi-Domain Management Server, run the commands on the MDS level.
