Vagrant conection timeout [UPD]

If Vagrant shows the message on vm start this means that virtual machine can't boot. And there is no case to connect through SSH.

As the solution you can try to view the VM state in GUI. Paste the code in Vagrantfile.local file:

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

If the problem appears while network is setting up change the settings of the first Network Adapter. Check the checkbox "Cable Connecter":

Settings -> Network -> Adapter 1 -> [v] Cable Connected
