Errors,please help

I want to configure a test cluster
Here is my node 2 configuration information:

cluster.name: esapp
node.name: node-2
node.master: false
node.data: true
network.host: 0.0.0.0
discovery.zen.ping.unicast.hosts: ["192.168.1.171:9200", "192.168.1.167:9200"]
discovery.zen.minimum_master_nodes: 2

Error information is thrown when node 2 starts:

please help me ,
I'm a beginner.
thank you

Communication within the cluster uses port 9300, not 9200.

With this setting you should have 2 or 3 master eligible nodes. Given that you have set node.master to false for this node and only listed 2 nodes, this may be a problem as well.

Please don't post images of text as they are hardly readable and not searchable.

Instead paste the text and format it with </> icon. Check the preview window.

OK , Thank you for your hint
