Unable to access Internet from an EC2 instance


My instance ID is: i-0e5a2c191d4ff1b02
This instance is in a public subnet in a custom VPC. The subnet is associated to the route table that has the route to Internet via Internet Gateway.
DNS resolution is working.

I am able to logon to the instance via SSH.

However, from the instance, outoging connections to the Internet is not working.

ping google.com
PING google.com ( 56(84) bytes of data.
--- google.com ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 6999ms

Can't connect to Yum repositories.

What could be the issue?

I reviewed the networking configuration after having a cup of coffee.
Recently, I had accidentally removed the outgoing connections in the attached security groups. I undid the change and all is well.
