Have you set your secret and key for LinkedIn and Twitter in your .py settings?
Once this is done, you may need to set redirect URLs with these providers.
I tested with google and fixed the access settings for the Google API.
I changed the redirect URLs to http://localhost:8000/complete/google-oauth2/
UPDATE: I am having problems with LinkedIn on oauth1 and 2. There is no way to get the required API key in the request. I tried to make hard code in the oauth1_auth.py request_oauthlib file, but haven’t done it yet.
UPDATE 2: Twitter worked for me, making sure that my Twitter developer application settings “Allow this application to log in using Twitter” were checked, and my consumer key and secret settings were set in my .py settings, for example:
# TWITTER # SOCIAL_AUTH_TWITTER_KEY = '<...>' SOCIAL_AUTH_TWITTER_SECRET = '<.....>'
