Unable to Connect to EC2 Instance and Ping Timeout

Question

I am unable to connect to my EC2 instance even though the instance status shows it is running. Ping also does not receive any response. There are no error messages or warnings. I have tried restarting the instance, but the issue persists. I am receiving the error message "Failed to connect to your instance. Error establishing SSH connection to your instance. Try again later."

do this steps
**on ec2:**
* check the security group associated with the instance is listening SSH and ICMP
* check if the instance is in a public subnet, otherwise you won't be able to connect
* check if the instance has a public IP associated or an Elastic IP

**on VPC:**
* [Check the public subnet has an Internet Gateway attached, and the routing table is well configured](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html) 
* Check the VPC Network ACL and look if you have anyone denying traffic to the subnet

probably with this steps you will be able to identify the issue and fix it
