Issue setting AWS EFS on rancher

I am trying to test Rancher AWS EFS catalog.
My Rancher instances are using rancher os, as that was my only option to bootstrap the instance using the AWS Machine driver.

Rancher instances and EFS are hosted within the same VPC / Network

convoy-efs_convoy-efs_1 is stuck at initialising status
and the logs shows : failed: Connection timed out

Any help is much appreciated.
Thanks in advance.
