To follow on to @lfender6445 and @SAURABH answers --

My problem was also the fact that after upgrading to Vagrant 2.2.2 Apache2 was running as a web server when the guest booted. In the past I only had nginx as a web server.

vagrant ssh into the box and run the following command to disable Apache2 from starting up whenever the guest box boots:

sudo update-rc.d -f apache2 remove

Exit ssh, vagrant halt, vagrant up. Problem solved.
