RabbitMQ Cluster failed to start

I am deploying RabbitMQ using Operator in Openshift 4.8 environment.   Using cluster-operator.yaml, I was able to deploy rabbitmq operator and rabbitmqcluster instance successfully in my prototype environment.    However, same exact code and image failed in Our Production Environment.   Operator deployed and does not seem to have any issue but rabbitmqcluster instance failed to start.   Only difference between two environment is Production is Air-Gap environment (No internet connection).   

When it is starting, all feature flags are unchecked and plug-ins failed to start.   

Help is very appreciated.   I attached the statefulset overrride yaml that I used to deploy.

Thanks.
