我正在使用celery 创建任务，但是过了一段时间redis返回一个错误

Traceback (most recent call last):

据我所知，任务失败时就会出现这样的问题。需要注意的是，我使用的是docker compose。我附上docker-compose.yml的摘录：

web:
    build:
      context: .
      dockerfile: compose/django/Dockerfile
    restart: always
    depends_on:
      - db
    volumes:
      - ./src:/src
    expose:
      - "8000"
    links:
      - redis
    env_file:
      - ./.envs/.django
    networks:
      - djangonetwork

redis:
    image: redis:alpine
    restart: always
    environment:
     - REDIS_REPLICATION_MODE=master
    ports:
      - "6379:6379"
    networks:
      - djangonetwork

networks:
  djangonetwork:
    driver: bridge

摘自settings.py：

CELERY_BROKER_URL = 'redis://redis:6379/0'
CELERY_RESULT_BACKEND = 'redis://redis:6379/0'

如何让celery 重新连接到redis没有任何问题？我是新来的，请帮忙。如果有必要，我可以补充这个问题
