Where are you trying to log in FROM? This will affect how the security group is configured, which I also need to know from you please. Without knowing what you’re doing, there’s nothing I can check.

It sounds like you have not configured your EC2 instance correctly; either the keys are not set up right, or the security group is not set up correctly. You may want to try one of our AWS courses. The first part of this course might be enough to get you started. Since you’re using the playground, you already have access to this course, so it’s a good way to learn the basics here.
