Magento – Magento refusing to connect after installation

I am using Magento 2 Developer's Guide to learn magento. Following the instructions for setting up the local environment I used Vagrant to install and run magento on a UNIX box. The VagrantFile executes fine and from the execution logs it looks like magento is installed and the server is up.

1) Here's how we've defined the ip info. in vagrant file :

config.vm.network "private_network", ip: vagrantConfig['ip']

2) ip value in the config file :

ip: 192.168.10.10

3) I then modified the hosts file on my host machine to include this :

192.168.10.10   magento.box

Here's what I get when I try to access magento installation from the browser :

Any thoughts on how to get this to work ? I am out of ideas on this.
