AWS EC2-LINUX “Network connection refused” - Error

As part of AWS certification projects, I have created AWS environment for my DEV and QA. Both the environments are created using the same CloudFormation template. DEV Environment is up and running. But I am unable to launch the QA Instance due to which our testing stopped.

When I try to login to the QA Machine it says

Network connection refused
I have checked the security groups opened port 22 on the machine. I have checked the VPC Configurations and NACLS. Everything looks fine.

What might be the issue?latest?d=yIl2AUoC8zA latest?i=x90QHOVduMY:U4nbRkDC9lA:F7zBnMy latest?i=x90QHOVduMY:U4nbRkDC9lA:V_sGLiP latest?d=qj6IDK7rITs latest?i=x90QHOVduMY:U4nbRkDC9lA:gIN9vFwx90QHOVduMY
