elasticsearch - NoRouteToHostException:在集群上运行Elasticsearch时没有路由到主机错误

Question

我在elasticsearch.yml中具有以下配置-

服务器1:-

cluster.name: rhel
node.name: "node-1"
network.host: 172.23.83.12
discovery.zen.ping.unicast.hosts: ["172.23.96.25"]
node.data : true
node.master : true 
discovery.zen.ping.multicast.enabled: false

服务器2:-

cluster.name: rhel
node.name: "node-2"
network.host: 172.23.96.25
discovery.zen.ping.unicast.hosts: ["172.23.83.12"]
node.data : true
node.master : true 
discovery.zen.ping.multicast.enabled: false

在具有两个节点的群集(RHEL系统)上运行ES时，出现以下错误，

在这之后，我不得不在两台计算机上都禁用了防火墙，然后它仍然可以正常工作。
