We have a production server working perfectly in the process of SSO with OpenID Connect clients for iOS and Android apps. But unfortunately, when we upgrade the Gluu version of our QA server from version 4.1 to 4.2.3, the clients for iOS and Android are failing when we try to logout, the server returns this error: `{"error_description": "The provided id token (or access token) or session state are invalid or were issued to another client.", "error": "invalid_grant_and_session"}` The clients are setup in the same way in both servers: **Production (Gluu Server 4.1):**   **QA (Gluu Server 4.2.3, where logout fails):**   Any ideas about what's going on? Kind regards!!
