Having all sorts of issues getting my cluster to work properly. using 7.6.1

On node1 I'm able to set my passwords on my machine without error. On node 2 and 3 I get

./elasticsearch-setup-passwords interactive

Failed to determine the health of the cluster running at [http://10.10.10.28:9200](http://10.10.10.28:9200)  
Unexpected response code [503] from calling GET [http://10.10.10.B:9200/\_cluster/health?pretty](http://10.10.10.B:9200/_cluster/health?pretty)  
Cause: master\_not\_discovered\_exception

It is recommended that you resolve the issues with your cluster before running elasticsearch-setup-passwords.

Node set up. this is set up on all machines. from everything I read this is correct way to set up.

------------------------------------ Node -----------------------------------

# 

# Use a descriptive name for the node:

# 

node.name: logs1

# 

# Add custom attributes to the node:

node.master: true  
node.data: true

# --------------------------------- Discovery ---------------------------------

# 

# Pass an initial list of hosts to perform discovery when this node is started:

# The default list of hosts is ["127.0.0.1", "[::1]"]

# 

#discovery.seed\_hosts: ["host1", "host2"]  
discovery.seed\_hosts: ["10.10.10.A", "10.10.10.B", "10.10.10.C"]

# 

# Bootstrap the cluster using an initial set of master-eligible nodes:

# 

cluster.initial\_master\_nodes: ["10.10.10.A", "10.10.10.B", "10.10.10.C"]

# 

#to avoid split brain ([Master Eligible Node) / 2 + 1])  
discovery.zen.minimum\_master\_nodes: 2
