Hi,  
I have a cluster with three node.  
When master node is turned off , I can't connect to any of nodes with their addresses.

MasterNode: 0.0.0.0:9200, Node2: 0.0.0.0:9201, Node3: 0.0.0.0:9202

with this configuration:

node.name:es01  
cluster.name:es-docker-cluster  
discovery.seed\_hosts:es02,es03  
bootstrap.memory\_lock:true

* * *

node.name:es02  
cluster.name:es-docker-cluster  
discovery.seed\_hosts:es01,es03  
bootstrap.memory\_lock:true

* * *

node.name:es03  
cluster.name:es-docker-cluster  
discovery.seed\_hosts:es01,es02  
bootstrap.memory\_lock:true

Then sharing the connection error you are getting would be helpful.
