Google OpenId: No OpenID endpoint found (intermittent)
Usually using the Google OpenId works fine, thousands of times a day, then it will start intermittently going wrong and timing out for an hours or so (some requests will validate but not all). Repeated validation will eventually work. Error messages are: Event code: 200000 Event message: No OpenID endpoint found. : https://www.google.com/accounts/o8/id Sequence contains no elements Adding in log4net yields: DotNetOpenAuth.Yadis: Error while performing discovery on: "https://www.google.com/accounts/o8/id": DotNetOpenAuth.Messaging.ProtocolException: Error occurred while sending a direct message
