Compose: Docker-compose: keep on getting can't "This site can’t be reached"

[Gardezi1]

Hello, guys, I'm kind of new to this.

I've created a Docker File

FROM node:7
# Working directory for application
WORKDIR /usr/src/app
# Binds to port 7777
EXPOSE 7777
# Creates a mount point
VOLUME [ "/usr/src/app" ]

and this is my docker-compose.yml file

version: "2"
services:
  redis:
    image: "redis"
  postgres:
    image: "postgres:9.4"  
  web:
    build: .
    ports:
     - "4000:4000"
    volumes:
     - .:/usr/src/app
    depends_on:
      - postgres
      - redis
    command: ["npm", "start"]

Now I ran docker-compose up -d and I'm not getting any error. But the problem is when I try to access it using this url 0.0.0.0:4000 it throws me this error "this site can't be reached"

Can you guys help me out thanks

Please head over to the forums for support requests. That said, using docker-compose up without the -d flag would probably yield more information about what might be going wrong with your app.
