I tried on different internet connections, so I don't think NAT is there.

PS: I am not a first time ec2 user, used it before.

Are you connecting from an EC2 instance? Your security group only allows connections from systems in the same security group. Is this what you intended? — John Hanley
Nope I wasn't . I see. changed to 0.0.0.0/0 and now it works. Thanks — ishandutta2007

Changed Security Group's source from sg-57710f2a to 0.0.0.0/0 Now it works. As @john-hanley pointed out sg-57710f2a allows only connection from within host under that Security Group not outside
