Run web app from localhost and headless stopped working - Browsers.RemoteItem

Hi.

I used to be able to run my web app locally and now I cannot anymore. Even the sample from Smartbear is not working.   How do you fix this? thanks

function Test_Chrome_Headless()
{
var server = "localhost";
var capabilities = {
browserName: "chrome",
screenResolution: "1920x1080"
};

var url = "https://services.smartbear.com/samples/TestComplete15/smartstore/";
Browsers.RemoteItem(server, capabilities).Run(url);

}
