Getting Internal Error 500 on redirect from the Identity Provider(Google)

Question

Hi All,
The issue happens when my web application is trying to obtain access token from the ACS using Google as Identity Provider.
The redirect to the Google authentication page works. It is possible to authenticate an user. However, after getting an authentication, accounts.google.com redirects the GET request to the redirect URL specified in the authentication request(mycompany.accesscontrol.windows.net/v2/openid).
And this request fails with HTTP status 500. The error details in the response body does not point to the reason of the problem:
An error occurred while processing your request.
HTTP Error Code:       500                 
Trace ID:              a1de23aa-b142-49e1-8e83-ee737ab61984                 
Timestamp:       2015-04-02 06:26:48Z
Could you please advice?
Thank you,

Hi Oleksiy,
Thanks for posting here!
I hope you are not using Open ID 2.0, as you might aware of Google moving to OpenID Connect, there is a requirement that you explicitly register your ACS Namespace as application with Google.
Token request failures that return HTTP 500-series error codes typically respond to retries. In some scenarios, the client is an application or service that makes automated requests to ACS. In other scenarios, such as web-based federation that uses the WS-Federation
protocol, the client is a web browser and the end-user must retry the operation manually.
