Facebook login suddenly stoped working. https://api.ionic.io/auth/integrations/facebook

I have an Ionic v2 app with Facebook login implemented, everything was working fine until recently. Now when i try to login using Facebook the App shows an error saying something about the Oauth URL. I think it has to do with the “Valid OAuth Redirect URIs” field in Facebook developer console; currently the value i have setted for this field is “https://api.ionic.io/auth/integrations/facebook”.
Is that value still valid?
