Redis slave is not able to connect to the Master in AWS EC2 Kubernetes Cluster

Question

When I allow particular port in AWS security Groups, Slaves are not connecting to the master but when I allow all traffic in security groups it's connecting and working fine.

Please help me on this, I want to allow only particular port in the security group and slaves(replics) should run .

Thank you.
