Как настроить кластер в Elasticsearch?

Хочу настроить кластер из 3-х машин (2 дата ноды, 1 мастер). На данный момент пытаюсь настроить минимум из 1 дата и мастер ноды. Порты пришлось поменять в силу специфики сети, но думаю проблема не в этом

Конфиг мастер ноды.

version: '3.9'
services:
  master:
    image: elasticsearch:8.1.1
    container_name: master
    environment:
      - node.name=master
      - cluster.name=elastic-cluster
      - network.host=0.0.0.0

      - discovery.seed_hosts=10.126.107.238:1029, 10.126.107.236:1029
      - cluster.initial_master_nodes=10.126.107.238

      - "node.roles=master"
      - ELASTIC_PASSWORD=${ELASTIC_PASSWORD}
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "bootstrap.memory_lock=true"
      - "xpack.security.enabled=false"
      - "xpack.security.transport.ssl.enabled=false"

    mem_limit: ${MEM_LIMIT}
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - master-data:/usr/share/elasticsearch/data
    ports:
      - 1028:9200
      - 1029:9300

volumes:
  master-data:
    driver: local

Конфиг дата-ноды

version: '3.9'
services:
  node01:
    image: elasticsearch:8.1.1
    container_name: node01
    environment:
      - node.name=node01
      - cluster.name=elastic-cluster
      - network.host=0.0.0.0

      - discovery.seed_hosts=10.126.107.238:1029, 10.126.107.236:1029
      - cluster.initial_master_nodes=10.126.107.238

      - "node.roles=data"
      - ELASTIC_PASSWORD=${ELASTIC_PASSWORD}
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "bootstrap.memory_lock=true"
      - "xpack.security.enabled=false"
      - "xpack.security.transport.ssl.enabled=false"
    mem_limit: ${MEM_LIMIT}
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - master-data:/usr/share/elasticsearch/data
    ports:
      - 1028:9200
      - 1029:9300

volumes:

    driver: local

Когда дата-нода пытается подключиться - выдаёт следующие логи
