How to make facebook login work?

Question

Facebook

with https it gives
Graph returned an error: Unable to load URL: The domain of this URL is not included in the list of application domains. To load this URL, add all of your application's domains and subdomains to the "Application Domains" field in your application's settings.
in the application settings, of course, the domain is registered. I've tried both http and https URLs. http works fine.

$_SERVER['SERVER_PORT'] = '443';
