Cannot connect to EC2 Instance through SSH (Connection timed out)

Question

I have an instance in AWS and running normally before. But today I can't connect into SSH and get response "Connection timed out".

I was search and what I get just about security group issue. In my case, SSH is enable to connect in inbound rule setting. And I also try to create new instance using same security group, it works fine.

如果您停止并重新启动您的实例，请检查实例的公共 IP，因为它会发生变化。
