Hazlecast clustering done on AWS EC2.Problem with Load Balancer

Hi,

I enabled hazlecast clustering on two aws ec2 instances. Both are working fine individually and I attached these instance under a load balancer.

I enabled the ports 7070,9090,5222,5223,5701,7443,9091.Now can not connect to chat servers via loadbalancer.Can i use load balancer for clustered nodes ?
