Using Runway Locally

Hi I'm trying to use a local version of Runway for testing but I get the following message:

Sorry, your license key isn't valid for this domain. This license key is for local testing only, so can only be used on a non-public domain.

I have a local dev environment set up on the domain loc.ebc

These are my 2 config files:

config.php

<?php
    switch($_SERVER['SERVER_NAME']) {

        case 'loc.ebc':
            include(__DIR__.'/config.local.php');
            break;

        default:
            include('config.production.php');
            break;
    }

    define('PERCH_RESFILEPATH', PERCH_PATH . DIRECTORY_SEPARATOR . 'resources');
    define('PERCH_RESPATH', PERCH_LOGINPATH . '/resources');

    define('PERCH_HTML5', true);
