"Empty reply from server" when trying to run webpack-dev-server inside a docker container with docker-compose on windows running docker-toolbox

I am having problems accessing a react container run with docker-compose inside docker-machine. I can curl the webpage inside the container, but I cannot access it inside docker-machine (or on the host's browser for that matter). The backend Golang container can be accessed from docker-machine and from the host's browser (as seen in the snippets, it returns a 404 not found).

In the docker-compose logs everything seems to be running smoothly, webpack-dev-server runs as expected, I just can't access it from outside the container.

I am using docker toolbox for windows.

Best to additionally describe the problem with some snippets.

Docker-compose file:

version: '2'
services:
    postgres:
        image: postgres
        environment:
            - POSTGRES_PASSWORD=postgres
    server:
        build: ./server
        command: gin
        volumes:
            - ./server:/go/src/app
        ports:
            - "8080:3000"
        environment:
            - POSTGRES_PASSWORD=postgres
    client:
        build: ./client
        command: npm start
        volumes:
            - ./client:/usr/src/app
            # mount node_modules as a workaround for it disappearing
            # after adding /client as a mounted folder
            - /usr/src/app/node_modules
        ports:
            - "9000:3000"

Dockerfile for the node container:

FROM node:6.5.0-slim

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

COPY package.json /usr/src/app/
ENV NODE_ENV development
RUN npm install

Output of the following commands inside docker-machine (default):

docker@default:~$ sudo iptables -t nat -L -n

Here comes the main problem:

docker@default:~$ curl 0.0.0.0:8080

404 page not found

Output of the following commands inside the node container:

Any help would be greatly appreaciated.
