Calico wait for etcd error Kubespray

I get the following error when trying to use Kubespray to install Kubernetes on an EC2 cluster

Anyone know why this might be? Here is a Github issue I filed with more info https://github.com/kubernetes-incubator/kubespray/issues/1466

TLDR; open both ports 2379 and 2380

I encountered this same issue and found that I needed to open two ports for etcd. The obvious port is 2379, because it is in the ansible error message. When I examined the logs for the etcd container on one of the failed nodes I found that it was trying to communicate with other etcd nodes on port 2380. I updated my security group to allow traffic on both ports and this error was resolved.
