Default message: SSO session expired; please start sign-in again
HTTP status:400(client)
Problem. The browser did not send the SSO session-binding cookie on callback. Cause. Cookies were cleared between init and callback, the flow spanned more than the state TTL, or the user started sign-in in one browser and completed in another. Fix. Start the SSO flow again in the browser that will complete it. HTTP 400.
