How do I test a localhost url in nightwatch js - selenium

Question

I am trying to run UI regression tests against a local project.
I am running the project with Browsersync, which ends up at localhost:3000.
I have tried setting the url to the directory of my distributed files but this also does not work. Internet Explorer opens but cannot connect to the page.
Here is my nightwatch.json
{
"src_folders" : ["nightwatch/tests"],
"output_folder" : "nightwatch/reports",
"custom_commands_path" : "nightwatch/commands",
"custom_assertions_path" : "nightwatch/assertions",
"page_objects_path" : "",
"globals_path" : "",
"selenium" : {
"start_process" : true,
"start_session" : true,
"server_path" : "C:\\Selenium\\selenium-server-standalone-2.52.0.jar",
"log_path" : "",
"host" : "127.0.0.1",
"port" : 4444,
"cli_args" : {
"webdriver.chrome.driver" : "",
"webdriver.ie.driver" : "C:\\Selenium\\IEDriverServer.exe"
}
},
"test_settings" : {
"default" : {
"launch_url" : "http://localhost",
"selenium_port" : 4444,
"selenium_host" : "localhost",
"silent": true,
"screenshots" : {
"enabled" : false,
"on_failure" : false,
"on_error" : false,
"path" : "test/screenshots/"
},
"desiredCapabilities": {
"browserName": "internet explorer",
"javascriptEnabled": true,
"acceptSslCerts": true
}
},
"chrome" : {
"desiredCapabilities": {
"browserName": "chrome",
"javascriptEnabled": true,
"acceptSslCerts": true
}
}
}
}
Here's my test
module.exports = {
before : function (browser) {
browser.resizeWindow(1024, 800);
},
'OOBE Homepage': function(browser) {
browser
.url('http://localhost:3000/index.html')
.waitForElementVisible('body', 5000)
.compareScreenshot('desktop-index.png')
.end();
},
};

Changing the launch_url to localhost:3000 worked.
