'Authentication failed in Github | python-social-auth

In my django project I use python-social-auth. I am tring to add social login with Github but unfortunately have next error:

Authentication failed: The redirect_uri MUST match the registered callback URL for this application.

Full error looks like this:

I registered application in Github and set set the callback URL as http://localhost:8000/complete/github/.

    },

Try to registrate callback URL on http://127.0.0.1:8000/ instead http://localhost:8000/

Solution 2:^[2]

The problem was with callback URL of Github. In my case I had language prefix inside URL, didnt expect that Github would be sensitive to that cause other provideres didnt raise error for link without prefix. I fount this post which describe how to show default language without path prefixes. I hope it will help someone who would face with such problem.
