Problem with Vagrant: timeout when connecting via SSH

I'm trying to get my box into the vagrant. When I give a vagrant up it executes everything correctly, but at the time of connecting with ssh , it gets timeout .

The stacktrace in powershell follows:

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.
PS C:\projetos_vagrant>

I also follow my Vagrantfile :

# -*- mode: ruby -*-
# vi: set ft=ruby :

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "hellobits"
  config.vm.box_url = "http://files.hellobits.com/vagrant/hellobits-trusty64-virtualbox.box"

  config.ssh.insert_key = false

end

Could someone give me a light?
