Solution for Instance Reachability Check Failed Error

 As part of a FinOps exercise, I was rightsizing a RHEL7 instance on EC2. It was using older family of m4, so I thought not only reducing the instance size but also upgrading instance family to get more bang for the buck. This change promised of savings of around USD$4000 per year just for this instance.
