Solution
Check the DR DB System Subnet security list Egress/Outbound rules is being opened to connect on 443. Though we have added same region all OCI services are added , it was not working as it is connecting to primary region services from DR. So, we have opened egree port on 0.0.0.0/0 to 443. This solved the issue.
