Explanation

The cause of the problem is that the operations engineer did not install Elastic Network Adapter (ENA) drivers before changing the instance type. The r4.16xlarge instance type uses the Intel 82599 network interface card (NIC), while the x2gd.16xlarge instance type uses the Elastic Network Adapter (ENA) NIC. The ENA driver is required for the new instance type to work https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstances.html
