Research direction

Start with the reported callback.html and the SC.connect() call in the AngularJS 1.6 controller, then inspect how SoundCloud SDK v3.1.2 handles the sign-in callback. Reproduce the Chrome and Firefox cross-origin errors and trace why the callback cannot reach the opener. Done means the callback completes without the browser security exception and the SC.connect() promise resolves.

Description

SoundCloud SDK v3.1.2
I registered my App approximately 1 year ago.

Today I discovered that my SoundCloud (SC) sign-in stopped working.

When I click on the button the SC pop-up appears with message "Allow “domain.com” access to your SoundCloud account?" I click connect and get the callback pop-up with the message "This popup should automatically close in a few seconds". The callback pop-up never closes. And in the dev console (for the callback pop-up) I see the following errors:

Chrome 55.0.2883.87 m (64-bit)

    VM2980 callback.html?code=3717208…&state=SoundCloud_Dialog_508d9:7 Uncaught DOMException: Blocked a frame with origin "http://domain.com" from accessing a cross-origin frame.

My callback.html:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>Connect with SoundCloud</title>
  </head>
  <body onload="window.setTimeout(window.opener.SC.connectCallback, 1);">
    <p>
      This popup should automatically close in a few seconds
    </p>
  </body>
</html>

The JavaScript function (in AngularJS 1.6 controller) that is triggered by a button on my page:

... 
      this.connect_sc = function () {
        debugger;
      // initiate auth popup
        SC.connect().then(function () {
          debugger;
          return SC.get('/me');
        }).then(function (me) {
          debugger;
          userPerma = me.permalink;
          setScUi(me.username, me.avatar_url);
          getPlaylists();
        });
      };
...

I tried to debug it putting some breakpoints. Here I don't get SC promise executed, it breaks only on the first debugger; after I click on my button.

Why is that and how to fix it?
