Recurly.js in sandboxmode - ThreeDSecure not returning anything after clicking “Succeed Test Authentication”

Question

I have problem with implementation of 3ds verification for Recurly, i have followed example from https://github.com/recurly/recurly-js-examples/blob/master/public/3d-secure/authenticate.html

My problem is that first iframe is loading correctly, but after clicking " Succeed Test Authentication" returns nothing to my threeDSecure.on('token' funcition(){}). It loads iframe with information "To complete your checkout process, please close this browser tab and return to your checkout form." Thanks for any responses.

My JS file https://pastebin.com/7zYDAEJs

// We expect this page to load with the following parameter pattern
// `/3d-secure.html#token_id=xxx&action_token_id`
// This is a simple parser for that pattern. You may use window.URLSearchParams
// instead if IE11 support is not needed
var hashParams = location.hash.substr(1).split('&').reduce(function (acc, i) {
  var [k,v] = i.split('=');
  acc[k]=v;
  return acc;
}, {});
// Configure Recurly.js
recurly.configure(recurly_key);
// In order to remain backend agnostic, this example passes the Recurly.js credit card token
// to this page via the URL hash. Here we add it to the form so that it will be passed
// to our backend
document.querySelector('#recurly-token').setAttribute('value',hashParams.token_id);

// Now we construct the 3-D Secure authentication flow

var risk = recurly.Risk();
var threeDSecure = risk.ThreeDSecure({ actionTokenId: hashParams.action_token_id });
var container = document.querySelector('#container-3ds-authentication');


// Handle errors that occur during 3-D Secure authentication
threeDSecure.on('error', error);
// 'token' is called when your user completes the 3-D Secure authentication flow
threeDSecure.on('token', function (token) {
    console.log(token);
    // place the result token in your form so that it will be submitted
    // when the customer re-submits
    document.querySelector('#three-d-secure-token').setAttribute('value',token.id);
    // Hide the container once we have a token
    container.style.display = "none";
    // Show the loading message
    document.querySelector('.three-d-secure-submitting-messagge').style.display = "block";
    // submit the form automatically
    recurly_form_verify.submit();
    });

    // Attach our 3D Secure session to the container
    threeDSecure.attach(container);
    // Show the container

    container.style.display = "block";
  // runs some simple animations for the page
  document.querySelector('body').classList.add( 'show' );
