Nginx & Docker: nginx fails to route to correct containers

I recently tried to set up nginx to route incoming traffic to different docker containers. Aside from site1, the other three sites seam to all route to one container, and sometimes that container changes on a restart.

After launching all of the docker containers, there doesn't seam to be any docker logs for nginx.

As far as I can tell all of the subsequent containers are running correctly (they are running Node.js)

my docker-compose.yml:

    version: '2'

services:
  resume:
    build:
      context: ../WebServer/
      dockerfile: Dockerfile
    volumes:
      - ../WebServer/app/publicFiles:/app/publicFiles
  globalmedical:
    build:
      context: ../globalMedical/
      dockerfile: Dockerfile
    volumes:
      - ../globalMedical/app/publicFiles:/app/publicFiles
  webjcl:
    environment:
      - NODE_DEBUG=fs
    build:
      context: ../webjcl/
      dockerfile: Dockerfile
    volumes:
      - ../webjcl:/app
  mongo:
    image: 'mongo:3'
    depends_on:
      - webjcl
  hack:
    build:
      context: ../Hack/
      dockerfile: Dockerfile
    volumes:
      - ../Hack/app/publicFiles:/app/publicFiles
  reverseproxy:
    links:
      - resume:resume
      - globalmedical:globalmedical
      - webjcl:webjcl
      - hack:hack
    build:
      context: ./
      dockerfile: Dockerfile
    ports:
      - 80:80
    restart: always
