mongo-express: Persistent "Authentication Failed"

Hello my dear friends.

I’ve been trying to setup a docker container with MongoExpress + MongoDB all week long. I really tried fixing it using all information available on google, but I believe it exausted the possibilities of something obvious I’m missing. Here’s my docker-compose (I’m omitting whatever is not related to mongodb and mdb express):

mongo:
    image: mongo
    container_name: mongodb
    restart: unless-stopped
    env_file: .env
    environment:
      - MONGO_INITDB_ROOT_USERNAME=${MONGO_INITDB_ROOT_USERNAME}
      - MONGO_INITDB_ROOT_PASSWORD=${MONGO_INITDB_ROOT_PASSWORD}
      - MONGO_INITDB_DATABASE=auth
    networks:
      - education-network
    volumes:
      - ./strapidb:/data/db
    ports:
      - "27017:27017"

  mongo-express:
    image: mongo-express
    ports:
      - 8081:8081
    env_file: .env
    environment:
      - ME_CONFIG_MONGODB_ENABLE_ADMIN=true
      - ME_CONFIG_MONGODB_ADMINUSERNAME=${ME_CONFIG_MONGODB_ADMINUSERNAME}
      - ME_CONFIG_MONGODB_ADMINPASSWORD=${ME_CONFIG_MONGODB_ADMINPASSWORD}
      - ME_CONFIG_MONGODB_SERVER=${ME_CONFIG_MONGODB_SERVER}
      - ME_CONFIG_BASICAUTH_USERNAME=${ME_CONFIG_BASICAUTH_USERNAME}
      - ME_CONFIG_BASICAUTH_PASSWORD=${ME_CONFIG_BASICAUTH_PASSWORD}
      - ME_CONFIG_MONGODB_PORT=${ME_CONFIG_MONGODB_PORT}
    depends_on:
      - mongo
    links:
      - mongo
  networks:
      - education-network

networks:
  education-network:
    driver: bridge

Here’s my .env file (it’s ok about passwords, I’ll change them later, just for the sake of debugging this issue):

DATABASE_CLIENT=mongo
DATABASE_NAME=strapi
DATABASE_HOST=mongodb
DATABASE_PORT=27017
DATABASE_USERNAME=strapi
DATABASE_PASSWORD=password
MONGO_INITDB_ROOT_USERNAME=admin
MONGO_INITDB_ROOT_PASSWORD=pass
ME_CONFIG_MONGODB_ADMINUSERNAME=admin
ME_CONFIG_MONGODB_ADMINPASSWORD=pass
ME_CONFIG_MONGODB_SERVER=mongodb
ME_CONFIG_BASICAUTH_USERNAME=admin
ME_CONFIG_BASICAUTH_PASSWORD=pass
ME_CONFIG_MONGODB_PORT=27017

It runs just fine:

root@educationexperience:~/services/strapi# docker-compose up -d
Creating network "strapi_education-network" with driver "bridge"
Creating strapi                 ... done
Creating mongodb ... done
Creating strapi_mongo-express_1 ... done

It is hosted at https://mdb.projetoalex.cc. It’s aparrently ok but no database is possible to create or edit, listing…

Here is the docker logs output:

Sorry for this long post. But I really tried all options and I’m stuck with this issue. Hoping you guys can help me debug and solve it.

Thanks in advance.
