Hi @handiansudianto
See sk167633 "Errors while loading Threat Prevention policy, Operation was unsuccessful" in the log.
Solution
Perform an IPS update on the Domain.
1. Log in to the Domain on the active CMA.
2. Select "Security Policies" tab and then Policy under Threat Prevention.
3. Click on "Updates" at the bottom and proceed with the IPS update. It can be done through client's internet connectivity or the Multi-Domain Managemet..
4. After the update is finished, push policy to the relevant Gateways and it should work now.
