Facebook blocking Heroku IP Addresses

[halfbeep]

Hi Andrej, this is a great piece of work and i'd like to pull to contribute adding Google and Instagram (after i've coded and tested) This issue is not related to your coded solution - but I'm interested in how you managed to run the video shown serving from heroku. Because of the dynamic IP on heroku I get this in the browser after Facebook auth authentication

{"message":"This IP can't make requests for that application.","type":"OAuthException"}

Facebook said it was resolved years ago here and it's also discussed here

Intrigued that you didn't see the error during your good work

Best wishes
Sh..

@halfbeep thanks for your positive feedback. I am happy my blog post + sample project are helpful. You are welcome to add login through Google and Instagram.

In regards to OAuthException issue, I think I got similar error and it was due to wrong configuration in facebook app settings. I wrote basic configuration steps here, but I can imagine facebook changes this configuration it in the future.
