Answer

This was asked 2 months ago but figure I add some info here..

Did the aws-node POD come up?
* check the aws-node POD is it up?
* check  the logs associated with it  (/var/log/aws-routed-eni)
* Are there enough IPs available?
* upgrade the aws cni add-on, restarted/scaled out the aws-node
* run the  /opt/cni/bin/aws-cni-support.sh on node to deeper analysis
