docker compose phpmyadmin php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution

I am trying to set up a docker-pod with laravel, mariadb, nginx, redis and phpmyadmin. The laravel webspace works finde but if i switch to port 10081 like configured in the docker-compose.yml i am not able to login with the root account.

it sais " mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution"

i already tried to configure a "my-network" which links all of the container, but if i understand docker right there is already a "defaul" network which does this. It didnt change the error message anyway.

here is my full docker-compose file

version: "3.8"
services:
  redis:
    image: redis:6.0-alpine
    expose:
      - "6380"

      MYSQL_ROOT_PASSWORD: secret
      MYSQL_DATABASE: laravel
    volumes:
      - db-data:/var/lib/mysql

  phpmyadmin:

    depends_on:

  node:

    working_dir: /app
    volumes:
      - ./:/app
    command: sh -c "npm install && npm run watch"

    Maybe your container cannot start because its volume contains incompatible data. It can happen if you downgrade the version of mysql or mariadb image.

    You can resolve the problem if you remove the volume and import the database again. Maybe you have to create a backup first.

    Make sure you have defined all attributes correctly for phpmyadmin container, in the current case there was the absence of -network definition

    phpmyadmin:
  image: phpmyadmin/phpmyadmin:latest
  container_name: phpmyadmin
  restart: always
  ports:
    # 8080 is the host port and 80 is the docker port
     - 8080:80
  environment:
    - PMA_ARBITRARY:1
    - PMA_HOST:mysql
    - MYSQL_USERNAME:root
    - MYSQL_ROOT_PASSWORD:secret
  depends_on:
    - mysql
  networks:
  # define your network where all containers are connected to each other
    - laravel
  volumes:
  # define directory path where you shall store your persistent data and config 
  # files of phpmyadmin 
    - ./docker/phpmyadmin
