The error is an authentication error. The reason for this may be one of the following:

  1. Either the instance is not using the same key pair.
  2. Maybe you are trying to connect to the wrong host
  3. Maye the username is incorrect. For ubuntu based AWS, the username is ubuntu else for other the username is ec2-user. 

Check with the above three conditions, you will be able to login.
