docker - Cant connect to Mysql on a container

Question

Im now trying to connect to mysql DB but i get this error

ERROR 1045 (28000): Access denied for user 'magento'@'localhost' (using password: YES)

I dont know what or where the problem is

this is the docker-compose I made

version: '2'
services:
  mysql:
    image: 'mysql:8.0.22'
    container_name: mysql
    environment:
      - MYSQL_DATABASE= magentodb
      - MYSQL_ROOT_PASSWORD= my-secret-pw
      - MYSQL_USER= magento
      - MYSQL_PASSWORD= my-secret-pw
    ports:
      - '3306:3306'
    volumes:
        - mysql-vol:/var/lib/mysql

  elasticsearch:
    image: 'elasticsearch:7.10.1'
    container_name: elasticsearch
    environment:
      - node.name=elasticsearch
      - discovery.type=single-node
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - elasticsearch-vol:/usr/share/elasticsearch/data
    ports:
      - '9200:9200'

  magento:
    build: .
    container_name: magento
    ports:
      - '80:80'
      - '443:443'
    depends_on:
      - mysql
      - elasticsearch

volumes:
  elasticsearch-vol:
    driver: local
  mysql-vol:
    driver: local

my question is, why I cant connect to mysql while I defined the mysql user and password as env. variables when creating the container?
