Vagrant share using wrong address

### Vagrant version
1.9.5

### Host operating system
OSX Sierra

### Guest operating system
Apache (I think)

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

Vagrant.configure(2) do |config|
# Define `web` as default
config.vm.define 'web', primary: true do |web|
# Box details
web.vm.box = 'deb/wheezy-amd64'
memory = 2048
cpus = 2

# Network
web.vm.network 'forwarded_port', guest: 80, host: 8080, auto_correct: true
web.vm.network 'forwarded_port', guest: 443, host: 4443, auto_correct: true

web.vm.network 'private_network', ip: '192.168.50.10'
web.vm.network 'public_network'

# Local sites directory
sites_directory = '~/Sites/buffalo' # Add absolute path to local sites directory here

# Synced directories
web.vm.synced_folder '.', '/vagrant'
web.vm.synced_folder sites_directory, '/vagrant-nfs', type: 'nfs'
web.bindfs.bind_folder '/vagrant-nfs', '/var/www', # Use vagrant-bindfs to re-mount directory
:owner => 'www-data',
:group => 'www-data'

# http://parallels.github.io/vagrant-parallels/docs/configuration.html
web.vm.provider 'parallels' do |v, override|
override.vm.box = 'parallels/debian-7.8'
v.memory = memory
v.cpus = cpus
end

# https://docs.vagrantup.com/v2/vmware/configuration.html
web.vm.provider 'vmware_fusion' do |v, override|
override.vm.box = 'thinktainer/debian-7.8-amd64'

end

# http://parallels.github.io/vagrant-parallels/docs/configuration.html
config.vm.provider 'parallels' do |v|

end

# Ansible provisioning
config.vm.provision 'ansible_local' do |ansible|
ansible.playbook = './ansible.yml'
ansible.groups = {'webservers' => ['web']}

# Support passing additional args to ansible, e.g. to run only certain tagged tasks

end
end
```

So for some reason vagrant share is now using:
Local machine address: 127.0.0.1
```Russells-iMac:vagrant Russ$ vagrant share --http 80 --name 1994
==> web: Detecting network information for machine...
web: Local machine address: 127.0.0.1
web:
web: Note: With the local address (127.0.0.1), Vagrant Share can only
web: share any ports you have forwarded. Assign an IP or address to your
web: machine to expose all TCP ports. Consult the documentation
web: for your provider ('virtualbox') for more information.
web:
web: Local HTTP port: 80
web: Local HTTPS port: disabled
web: Port: 2222
web: Port: 4443
web: Port: 8080
web: Port: 2200
==> web: Checking authentication and authorization...
==> web: Creating Vagrant Share session...
web: Share will be at: 1994
==> web: Your Vagrant Share is running! Name: 1994
==> web: URL: http://1994.vagrantshare.com
==> web:
==> web: You're sharing your Vagrant machine in "restricted" mode. This
==> web: means that only the ports listed above will be accessible by
==> web: other users (either via the web URL or using vagrant connect).
```

When before it was using:
Local machine address: 192.168.50.10

```==> web: Detecting network information for machine...
web: Local machine address: 192.168.50.10
web: Local HTTP port: 80
web: Local HTTPS port: disabled
==> web: Checking authentication and authorization...
==> web: Creating Vagrant Share session...
web: Share will be at: 1994
==> web: Your Vagrant Share is running! Name: 1994
==> web: URL: http://1994.vagrantshare.com
```

Which means none of the vagrant shared sites are working. However the local versions are still working, so http://www.1994.192.168.50.10.nip.io for instance is still working, and new projects work fine. Its only vagrant share thats using the wrong address

Any ideas?

Thank-you
