Redis – could not connect to server: Connection refused Is the server running on host "database" (172.19.0.3) and accepting TCP/IP connections on port 5432?

I am trying to run Django tests on Gitlab CI but getting this error, Last week it was working perfectly but suddenly I am getting this error during test run

django.db.utils.OperationalError: could not connect to server: Connection refused
Is the server running on host "database" (172.19.0.3) and accepting
TCP/IP connections on port 5432?

My gitlab-ci file is like this

image: docker:latest
services:
  - docker:dind

variables:
  DOCKER_HOST: tcp://docker:2375
  DOCKER_DRIVER: overlay2

test:
  stage: test
  image: tiangolo/docker-with-compose
  script:
    - docker-compose -f docker-compose.yml build
    - docker-compose run app python3 manage.py test

my docker-compose is like this:

version: '3'
volumes:
  postgresql_data:
services:
  database:
    image: postgres:12-alpine
    environment:
        - POSTGRES_DB=test
        - POSTGRES_USER=test
        - POSTGRES_PASSWORD=123
        - POSTGRES_HOST=database
        - POSTGRES_PORT=5432
    volumes:
        - postgresql_data:/var/lib/postgresql/data
    healthcheck:
        test: ["CMD-SHELL", "pg_isready -U $${POSTGRES_USER} -e "SHOW DATABASES;""]
        interval: 5s
        timeout: 5s
        retries: 5
    ports:
        - "5432"
    restart: on-failure

  app:
    container_name: proj
    hostname: proj
    build:
      context: .
      dockerfile: Dockerfile
    image: sampleproject
    command: >
      bash -c "
        python3 manage.py migrate  &&
        python3 manage.py wait_for_db  &&
        gunicorn sampleproject.wsgi:application -c ./gunicorn.py
      "
    env_file: .env
    ports:
      - "8000:8000"
    volumes:
        - .:/srv/app
    depends_on:
       - database
       - redis

So why its refusing connection? I don’t have any idea and it was working last week.
