Angular Implicit Callback causing browser to stall

I am following the angular quickstart guide with my own dummy project. I am the point where my login button gets me to the login screen, authenticates, then the browser stalls out trying to redirect back to the implicit callback. As far as I can tell, I have set everything the way the guide has instructed. I am using the Visual Studio 2017 Angular app template.

The logs on my server indicate successful authentication.

Any ideas on what I should look at?

Quick start guide:

Can you try cloning one of the Angular sample projects, changing the settings to match your Okta app, and see if that works?
