Not able to connect aws redis with ec2 on same VPC

I have created AWS ElastiCache redis server and configured with EC2 instance, but somehow I am not able to connect Redis via EC2 instance.

I have assigned the same security group as well.

here is my configuration

Error I am facing is Redis::CannotConnectError: Error connecting to Redis on some-prod.dhgdjw.0001.usw2.cache.amazonaws.com:6379 (Redis::TimeoutError)

Any help will be highly appreciated.
