Trello.authorize() has stopped working for me?

[nordicair_admin]

When I use Trello.authorize() after enabling a custom Power-Up I first get a page where I have to login 

After that an Allow page:

And after that only a blank page... Success or error is not returned.

window.Trello.authorize({
    type: "popup",
    name: "my app",
    interactive: true,
    expiration: "never",
    success: function () {console.log("Success") },
    error: function () { console.log("fail"); },
    scope: { write: true, read: true },
});

The problem has appeared now but it has worked before - Any Ideas?
