Hi, Sorry for asking this again because I think there are several threads about this problem. I have tried the common solution but I still cannot ping to EC2. I'm not sure if I have to make some more configuration. Can you help me?
Here's my setting for inbound rules:

The instance public address is: ec2-3-19-75-53.us-east-2.compute.amazonaws.com
In command prompt, I run: ping ec2-3-19-75-53.us-east-2.compute.amazonaws.com
So normally, it is supposed to ping successfully, right?
Thank you
