I have a rather strange issue i'm not sure how to fix or if i can even fix it.
I've done some research into the issue but can't find an answer to what's causing it.
I'm following a rather simple guide at http://www.asp.net/mvc/tutorials/mvc-5/create-an-aspnet-mvc-5-app-with-facebook-and-google-oauth2-and-openid-sign-on
and after enabling SSL
and changing the controller
to require https i get the following error:
Server Error in '/' Application.

Turning off SSL
fixes the issue, I also know that commenting out the startup.auth
in app_start
fixes the issue on SSL
.
Does anyone know why this is happening?

Similar to Sandeep's answer, I also updated the cookie authentication provider. Except, instead of swallowing the error I threw the exception so you could see what the underlying problem was:
The underlying problem for me was that I had changed the model and forgotten to add a new migration.
