Please make sure that you have configured it on security group for port 22, you can refer it from the following link: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/authorizing-access-to-an-instance.html

Answer 2

Check for a firewall blocking access to this port or IP. It might be a firewall running on the client machine, the server machine or a network firewall running in the client network.
