Can't run asp.net app on os x with dnx . kestrel

I followed this tutorial to install tools to run asp.net on os x. I scaffolded the asp.net web application successfully, but and run all the commands the application isn't running.

macbook$ cd '/Users/macbook/Documents/Leisure/asp/webapp' ; /Users/macbook/.dnx/runtimes/dnx-mono.1.0.0-beta6/bin/dnx . kestrel
info    : [Microsoft.Framework.DependencyInjection.DataProtectionServices] User profile is available. Using '/Users/macbook/.local/share/http://ift.tt/1KG10ju' as key repository; keys will not be encrypted at rest.
Started

Everything seems fine, but when I go to localhost:5000 I get ERR_CONNECTION_REFUSED, even though kestrel is set at this url.

What's not right? how do I get my asp.net app working?
