Django Python Social Auth, Authentication Canceled by Facebook app

Question

I am trying to implement website login using Facebook credentials. I see different responses when I press Cancel on Facebook widget or Okay. When I press Cancel I see the following

    Environment:


    Request Method: GET

    Exception Type: AuthCanceled at /complete/facebook/
    Exception Value: Authentication process canceled

Which is predicatble. But when I press Okay I see another error.

I am running the website locally on Ubuntu 14.04 apache web server with 80 port. I suspect wrong Facebook app setup but do not know what to debug.

Also, I can mention that Twitter login is working on the same setup.

Please advise!

Answer 1

I did wrong Facebook app setup. In the Security / Server IP Whitelist I put 127.0.0.1 address. The problem was gone after removing this address (blank space is okey).

Answer 2

Check the redirect URL. I had wrongly specified redirect URL along with client ID while making post request. For Facebook redirect URI is optional. Try removing that and it will work fine.
