How to access "http://localhost" from a Docker container in Windows?

I have a set of containers running in Windows 10 with Docker, this is the output of docker-compose ps:

> docker-compose ps
     Name                    Command               State                          Ports
--------------------------------------------------------------------------------------------------------------
db_mysql          docker-entrypoint.sh mysqld      Up      3306/tcp
elk               /usr/bin/supervisord -n -c ...   Up      0.0.0.0:81->80/tcp
php71-fpm-nginx   /config/bootstrap.sh             Up      443/tcp, 0.0.0.0:80->80/tcp, 0.0.0.0:9001->9001/tcp

And this is the output of docker inspect:

> docker inspect php71-fpm-nginx

I am trying to access http://localhost but I can’t. I’ve tried also using the container IP meaning http://172.18.0.3 and doesn’t work either.

When I say I can’t it means the following message:

This site can’t be reached
172.18.0.3 took too long to respond.

The same container works perfectly in Linux.

This is the content of c:\Windows\System32\drivers\etc\hosts file:

# localhost name resolution is handled within DNS itself.
	127.0.0.1       localhost

What I am missing here?

Having a similar issue, did you figure this one out? Was it a conflicting network device or similar on the host?
