Failed to run patroni

I have follow this tutorial: https://linode.com/docs/databases/postgresql/create-a-highly-available-postgresql-cluster-using-patroni-and-haproxy/ , in order to set up Highly Available PostgreSQL Cluster Using Patroni and HAProxy.

But when I try to start patroni I get this error:

ubuntu@sudo patroni /etc/patroni.yml

etcd congiguration:

ETCD_ADVERTISE_CLIENT_URLS="http://privateIPofetcd:2379"

ETCD_INITIAL_CLUSTER_TOKEN="cluster1"

Of course, I have the real ips in privateIPoffirstnode, privateIPofsecondnode etc.

So, does anyone know what this error means?
