No communication inter node in cluster

Elastic Stack Elasticsearch
1

hello i have a probleme in the communication inter node in cluster.
My configuration:

Node1:
cluster.name: test
node.name: node1
node.master: true
node.data: false
network.host: 192.168.93.140
transport.tcp.port: 9300-9400
discovery.zen.ping.unicast.hosts: ["192.168.93.140", "192.168.93.143"]

Node2:
cluster.name: test
node.name: node2
node.master: true
node.data: false
network.host: 192.168.93.143
transport.tcp.port: 9300-9400
discovery.zen.ping.unicast.hosts: ["192.168.93.140", "192.168.93.143"]

servers run with centos 7 :

systemctl stop firewalld
systemctl disable firewalld

and selinux mode permissive

result on my node 1 :

{
"name" : "node1",
"cluster_name" : "test",
"cluster_uuid" : "vS3ikxY5Tk2FO1h2nFsMmg",
"version" : {
"number" : "5.4.1",
"build_hash" : "2cfe0df",
"build_date" : "2017-05-29T16:05:51.443Z",
"build_snapshot" : false,
"lucene_version" : "6.5.1"
},
"tagline" : "You Know, for Search"
}

result on my node 2 :

{
"name" : "node2",
"cluster_name" : "test",
"cluster_uuid" : "na",
"version" : {
"number" : "5.4.1",
"build_hash" : "2cfe0df",
"build_date" : "2017-05-29T16:05:51.443Z",
"build_snapshot" : false,
"lucene_version" : "6.5.1"
},
"tagline" : "You Know, for Search"
}
