Disqus oAuth on Flask : CSRF verification failed error

[anushshetty]

I am using the disqus-python API to do oAuth authentication for my application.

This is the script I am using in my application, https://github.com/disqus/DISQUS-API-Recipes/blob/master/python/oauth/oauth_example.py

The authentication success but I get a 500 Internal Server error after authentication on my browser. But when I try it from links, I see "CSRF verification failed (403)". Can anyone tell me what could be the issue here?
