I was trying to search for an old message in my inbox on Stack Overflow and clicked on all Items link which redirected me to https://stackexchange.com/users/login which displays the following page:

This is the first time I am trying to login/signup on Stack Exchange. I never used it before, and I currently use Stack Overflow and Meta Stack Exchange with my Facebook login, and I wanted to use the same one here to sign-up, but as soon as I click on the OpenID option for Facebook, the graphAPI throws an 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 sub-domains of your app to the App Domains field in your app settings."

And it redirects me to the following page:

Is this issue occurring for everyone or is it me only, or I am trying to do it the wrong way? Any guidance will be appreciated.

Turned out that we had a typo in the callback URL. It's fixed in production now.

Sorry about the delay, and thanks for the report!
