Django allauth and FaceBook authorization error, what can go wrong?

Question

Django

django-allauth==0.37.1
Configured properly. The keys fit.
When requested, the site shows authorization in facebook, but then, when facebook submits the key back, an error occurs.

Social Network Login Failure
An error occurred while attempting to login via your social network account.

No details. What can go wrong and where to dig?
Optional question: is allauth even alive?
UPD: They suggested how to debug ( https://stackoverflow.com/questions/40624344/djang...

Code: {{ auth_error.code }}, Error: {{ auth_error.exception }}

error retrieving access token: b'{"error":{"message":"Unable to load url: The domain of this url is not included in the list of application domains. To load this url, add all your application domains and subdomains to the \u00abApplicationDomains\ field u00bb in your application settings.","type":"oautheexception","code":191,"fbtrace_id":"c+j+fqmdlyc"}}'
This does not solve the problem, because, of course, the domain is in the list.
