I have an application that can login with Facebook, but a few days ago this feature stopped working and now displays the following message that is in the image attached, deleted the application I created on Facebook, created the hashes keys again, but the error continues to occur below, someone could help me in this question?
You need to confirm on the facebook Dashboard if the application package is correct, and remember that the hash for debug is different from the hash for release

Thank you very much @Leonardodias, I checked the package and managed a "Production keyhash", but still with the same problem.
