As you have already configured settings for client id and client secret correctly.
Make sure you have social account apps there in settings.py.
INSTALLED_APPS = [ # my apps ..... # pre installed apps ..... # installed apps ..... # social apps 'allauth', 'allauth.account', 'allauth.socialaccount', 'allauth.socialaccount.providers.google', ]
and if this is correct then problem maybe you have not restarted server after making changes.
ssh to server and the put following commands
$ sudo service gunicorn restart $ sudo service nginx restart
and if you use apache server then restart it accordingly.
If stiill not works may be your site it not integrated, put your site-id in settings.py
SITE_ID = 1
If still not works try changing your keys by reset and get new keys
Hope it works then.
Most Importantly restart your server again
