Facebook OAuth "The domain of this URL isn't included in the app's domain"

Question

Let me first start with saying I've searched for an answer to this question for quite some time...

I'm trying to setup Facebook OAuth to work with my application that is being developed locally on my machine. Everything was working perfect with Facebook authorization UNTIL I moved from using localhost to another domain name (still local to my machine.) Now I'm getting the following error.

Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings.

My hosts file contains 127.0.0.1 domain.dev (works perfect)

My redirect in my app (using Socialite) is http://domain.dev/auth/facebook/callback

In my Facebook App Settings...

• my App Domain is domain.dev
• my Site URL is http://domain.dev/
• my Valid OAuth redirect URIs is http://domain.dev/auth/facebook/callback

The URL at the time of the error message is..

https://www.facebook.com/v2.5/dialog/oauth?client_id=XXXXXXXXXXXXXXX&redirect_uri=http%3A%2F%2Fdomain.dev%2Fauth%2Ffacebook%2Fcallback&scope=email&response_type=code&state=0ztcKhmWwFLtj72TWE8uOKTcf65JmePtG95MZLDD

I'm at a loss of what the problem is...

In case someone comes across this and is looking for these settings (like I was)

You have to

1. On the left hand side, click "+Add Product" and select "Facebook Login" (it was at the top for me)
2. See the new settings available on the left hand side
3. You will now have these OAuth settings on that "Product Settings"

Additional Info: Make sure to add the Callback URL like http://localhost:3000 to the Valid OAuth redirect URIs field on the settings page of Facebook Login
