default: Warning: Remote connection disconnect. Retrying

Question

When I run vagrant up, I get:

D:\GitHub\website\rails-dev-box>vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'ubuntu/trusty32' is up to date...

    default: Warning: Remote connection disconnect. Retrying...

This warning will be for ever ..

What I've noticed is that if I started the VM manually ( without vagrant ) it will work without any delay, but only If I enabled Adapter 2 at VM settings like this: How can I enable Adapter 2 of VM when using vagrant up ?

EDIT

Vagrantfile is:

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant::Config.run do |config|
#     config.vm.network :hostonly, "192.168.50.4"
end



Vagrant.configure('2') do |config|

  config.vm.box      = 'ubuntu/trusty32'
  config.vm.hostname = 'rails-dev-box'
# config.vm.synced_folder ".", "/vagrant/web" #, type: "nfs"

config.vm.provider :virtualbox do |vb|
  vb.gui = true
end

 config.vm.boot_timeout = 120

 #  config.winnfsd.uid = 1
   # config.winnfsd.gid = 1

  config.vm.network :forwarded_port, guest: 3000, host: 1234

  config.vm.provision :shell, path: 'bootstrap.sh', keep_color: true
end

For me it turned out that patience was the answer.
I was getting the message (I got it 12 times) but I waited a couple of minutes and then it succeeded. When you say "this warning will be for ever .." How long did you wait?
