ubuntu VM with wordpress install redirects unexpectedly ( port forwarding 80 to 8080?)

I’ve got an Ubuntu 14 VM running on a windows 10 host.

I’ve installed nginx and using

  config.vm.network "forwarded_port", guest: 80, host: 8080

in my Vagrantfile I can see the default nginx page when I visit

127.0.0.1:8080 in my browser on the host machine.

With that working I installed wordpress in a folder so that it would appear as
http://127.0.0.1:8080/aqua/

that worked as well and the wordpress site is visible at the http://127.0.0.1:8080/aqua/ address in Windows 10

But a strange thing happens in my VM. I can wget the root of the server without an issue.

 wget localhost/
--2016-03-23 21:30:54--  http://localhost/
Resolving localhost (localhost)... 127.0.0.1
Connecting to localhost (localhost)|127.0.0.1|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 12 [text/html]
Saving to: ‘index.html.3’

100%[======================================>] 12          --.-K/s   in 0s

2016-03-23 21:30:54 (295 KB/s) - ‘index.html.3’ saved [12/12]

If I wget the ‘aqua’ subfolder where the wordpress is installed

 wget localhost/aqua
--2016-03-23 21:32:28--  http://localhost/aqua
Resolving localhost (localhost)... 127.0.0.1

I get redirected to port 8080.
both of these wget’s are on the guest ubuntu machine.

Could this be a symptom of my Vagrantfile?

  # config.vm.box_check_update = false

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  config.vm.network "forwarded_port", guest: 80, host: 8080

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on

  # Share an additional folder to the guest VM. The first argument is

  # Provider-specific configuration so you can fine-tune various

  # config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  # end
  #
  # View the documentation for the provider you are using for more
  # information on available options.

  # Define a Vagrant Push strategy for pushing to Atlas. Other push strategies
  # such as FTP and Heroku are also available. See the documentation at

I can’t see anything there that would cause a redirect on the guest machine.
Wordpress is causing a redirect on the guest machine but I’m still able to see the site on the host machine.
