Trouble setting up flynn demo

[Nick]

Greetings,

Not sure if this mailing list is still appropriate to use given how old it is, but it's linked in the repository so...

I am trying to set up the flynn vagrant demo. 

I have run the demo vagrant box running, but when I try to add the cluster from my client (Mac OS X) I get this error message:

Error writing CA certificate: Get https://controller.demo.localflynn.com/ca-cert: dial tcp 192.0.2.200:443: i/o timeout

Can someone point me in the right direction? 

I did not modify the vagrantfile and I can see the IP address is correct:

  config.vm.network "private_network", ip: "192.0.2.200"

A couple of other questions as I am getting started

1. How does the DNS resolve from demo.localflynn.com to this address?  I was surprised that it found the right address, but it did

2. I see there is a Vagrant file in the root of the flynn repository, and then there is the Vagrantfile in the demo file -- I used the latter.  Is the idea that the first would be used in production but the second is just preconfigured to quickly (and, ideally, easily! launch to test?)
