403 on Laravel Docker setup

I have been struggling to setup my dev enviroment based on Docker to run Laravel app. But it keeps showing me 403 Forbidden error

Below is my configuration. I tried to login to nginx container and tail -f /var/log/nginx/error.log but it does not write anything. Please guide me what i am doing wrong here.

Thanks

docker-compose.yml

version: '2'
services:
  nginx:
    build: ./nginx
    ports: 
      - "8000:80"
    volumes:
      - ./app:/usr/share/nginx/html
    environment:
      TERM: xterm
    links:
      - php
  php:
    build: ./php
    volumes:
      - ./app:/usr/share/nginx/html
    environment:
      TERM: xterm
    links:
      - mysql
  mysql:
    build: ./mysql
    volumes:
      - ./mysql/data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root

Simple route to localhost:8000

Route::get('/', function () {
    return 'Hello World';
});
