python-social-auth and github, I have this error "The redirect_uri MUST match the registered callback URL for this application"
that worked 
Setting your domain to 127.0.0.1 in your hosts file should work, something like this
127.0.0.1   example.com
I'm using python-social-auth on a project to authenticate the user with Github.
I need to redirect the user depending on the link they use. To do that I'm using the next attribute on the url, and I didn't declare any redirect url on my github app neither in my django settings.
This is the href attribute I'm using for my link : {% url 'social:begin' 'github' %}?next={% url 'apply' j.slug %}
And the first time I click on it, I'm getting redirected to my homepage with this error in the url field : http://127.0.0.1:8000/?error=redirect_uri_mismatch&error_description=The+redirect_uri+MUST+match+the+registered+callback+URL+for+this+application.&error_uri=https%3A%2F%2Fdeveloper.github.com%2Fv3%2Foauth%2F%23redirect-uri-mismatch&state=Ui1EOKTHDhOkNJESI5RTjOCDEIdfFunt
But after first time the link work.
I don't know where is the problem, I hope someone can help me. Thanks
