ES with Azure cluster plugin not shows other nodes

I'm follow manual
from https://github.com/elasticsearch/elasticsearch-cloud-azure and have 3
nodes, but when i try to get cluster information by using:
curl http://100.86..:9200/_cat/health?v

getting: node.total = 1.

I tried to star over by manual, and got the same result.
When make request from one node to others get's standard result, but only
for that node.

What I'm doing wrong? Can somebody help me or tell about resolution?
