❔ "Cannot assign requested address [::1]:27017" when connecting to MongoDB on Docker.

I have a Docker Compose file with containers - backend: ASP.NET Core web API - mongo: MongoDB which looks like this:

version: '3.4'

services:
  backend:
    image: home-api
    ports:
      - "2154:2154"
    build:
      context: ./api
      dockerfile: ./api/Dockerfile

  mongo:
    image: mongo
    restart: always
    ports:
      - "2155:27017"
    volumes:
      - ./Data:/data/db
    environment:
      MONGO_INITDB_ROOT_USERNAME: home-api
      MONGO_INITDB_ROOT_PASSWORD: home-api

version: '3.4'

services:
  backend:
    image: home-api
    ports:
      - "2154:2154"
    build:
      context: ./api
      dockerfile: ./api/Dockerfile

  mongo:
    image: mongo
    restart: always
    ports:
      - "2155:27017"
    volumes:
      - ./Data:/data/db
    environment:
      MONGO_INITDB_ROOT_USERNAME: home-api
      MONGO_INITDB_ROOT_PASSWORD: home-api

With the API, I followed two tutorials: - https://learn.microsoft.com/en-us/aspnet/core/web-api/?WT.mc_id=dotnet-35129-website&view=aspnetcore-7.0 - https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-mongo-app?view=aspnetcore-7.0&tabs=visual-studio-code I then containerized it and started mongod in a ./Data directory. When connecting to the database (on the mongo container) with this appsettings.json

{
  "HomeDatabase": {
    "ConnectionString": "mongodb://home-api:home-api@mongo:27017/Home.Users?authSource=admin",
    "DatabaseName": "Home",
    "UsersCollectionName": "Users"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*"
}

{
  "HomeDatabase": {
    "ConnectionString": "mongodb://home-api:home-api@mongo:27017/Home.Users?authSource=admin",
    "DatabaseName": "Home",
    "UsersCollectionName": "Users"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*"
}

I recieve an error from the backend container. (attached) New to MongoDB, Docker, and ASP.NET. Let me know if you want any additional information.

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
