    Does this answer your question? [Cannot ping AWS EC2 instance](https://stackoverflow.com/questions/21981796/cannot-ping-aws-ec2-instance) – Aleksander Wons Nov 14 '20 at 12:57
  • Could be a security group not allowing traffic (default is deny everything) or a network ACL that restrict traffic (but the default is allow everything) – Julien B. Nov 15 '20 at 06:33
