ES 5.5.1 exception caught on transport layer:closing connection,java.io.IOException: Operation timed out

Elastic Stack Elasticsearch

I have a very urgent question，ask for help
this is my config file:
master:
network.host: 0.0.0.0
discovery.zen.minimum_master_nodes: 1
node.master: true
bootstrap.memory_lock: false
node.data: false
node.ingest: false
discovery.zen.ping.unicast.hosts: ["192.168.8.3:31300"]
node.name: "master01"
cluster.name: "esgroup"
http.cors.enabled: true
http.cors.allow-origin: "*"
network.publish_host: "192.168.8.3"
transport.tcp.port: 31300
transport.publish_port: 31300

data:
network.host: 0.0.0.0
discovery.zen.minimum_master_nodes: 1
node.master: false
bootstrap.memory_lock: false
node.data: true
node.ingest: false
discovery.zen.ping.unicast.hosts: ["192.168.8.3:31300"]
node.name: "data01"
cluster.name: "esgroup"
http.cors.enabled: true
http.cors.allow-origin: "*"
network.publish_host: "192.168.8.4"
transport.tcp.port: 9300
transport.publish_port: 9300

I use docker to deploy master and node nodes on two machines, the command is as follows：
master:
docker run -d --name elasticsearch -p 9200:9200 -p 31300:31300 -v /root/elasticsearch.yaml:/usr/share/elasticsearch/config/elasticsearch.yml elasticsearch:5.5.1-apline
data:
docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300-v /root/elasticsearch.yaml:/usr/share/elasticsearch/config/elasticsearch.yml elasticsearch:5.5.1-apline

It was successful at the beginning, but it will crash after the interruption, and then restart and then resume, and then crash again, so repeat

error:
