Docker Compose部署NATS服务出现CONNECTION_REFUSED问题求助

我用Docker Compose部署第二个包含5个服务的集群，为避免端口冲突使用了独立端口，主集群运行正常，但第二个集群的NATS服务出现CONNECTION_REFUSED错误。以下是相关信息：

docker-compose.yaml配置 #

version: "1"
    
services:
  api-gateway:
    build: ./api-gateway
    restart: always
    hostname: gateway
    env_file:
      - ./api-gateway/env/dev.env
    ports:
      - "8801:8801"
    networks:
      - lazar-network-dev-5

  nats:
    image: nats-streaming:0.17.0
    ports:
      - "4223:4223"
    command: ["--port", "4223"]
    networks:
      - lazar-network-dev-5


volumes:
  cache:
    driver: local

networks:
  lazar-network-dev-5:
    name: lazar-network-dev-5
    driver: bridge
    attachable: true
