Sequence contains no elements. No OpenID endpoint found

[Aly Boghani]

This code works perfect fine on local machine but on my staging servers I am getting this issue every now and then. And after few min, it will just go away.
I even increased time out in web.config

I've been having the exact same problem for the past 2-3 months now. It was fine for the over the last year but it just starting throwing these errors sporadically in 3 different environments (Test, UAT, Production). I've changed timeout values. I have switched from using the HostMetaDiscoveryService (UseGoogleHostedHostMeta = true) with my employers domain to simply using "https://www.google.com/accounts/o8/id". I've also tried changing the defaultProxy settings in my web.config. None of that has worked. It has been frustrating because it'll work fine for a few hours and then seemingly start throwing the same exception. And it won't occur in the different environments at the same time.

The error message from log4net is below:

Error while performing discovery on: "https://www.google.com/accounts/o8/id": DotNetOpenAuth.Messaging.ProtocolException: Error occurred while sending a direct message or getting the response. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Aly Boghani, do you by chance have your code running in an Azure Web Role or in Azure at all? I'm running my application in an Azure Cloud Service (a single web role, running on 2 instances). My current hypothesis is that it is a communication issue between Azure and Google. Prior to yesterday, the cloud service shared the same affinity group with a virtual network my employer has running. Then yesterday I've recreated the cloud service for all my environments, but chose "North Central US" instead of in the affinity group. I haven't seen the issue since then, but I'm going to give it a week or two to see if the issue has truly disappeared.

Hope this helps anyone who comes across the same issue.

Thanks,

Steven

I have been having a similar issue with our environments that are deployed in Azure cloud. I have attempted modifying the timeout values to no avail. I did notice that some days this error seems to appear more often than others. I am unsure yet if this correlates to days when we push up a new build to our environments or not.

Steven Kuhn, did you have any success with changing your affinity group?

here are the logs from log4net

I downgraded my amazon instance to windows 2008 instead of windows 2012 and it started working fine.

Chuck Rice: After recreating the Cloud Service inside the US North Central region instead of using the custom affinity group that my employer has for the same region, I haven't had a problem since. The next thing I want to try is to create a new affinity group just for my application and move the storage account and Azure SQL database to that same one. I'm not sure when I'll get to that, but at least it seems to be working now.

[Chuck Rice]

Well I can say for a certainty that the Affinity group solution will not solve my situation then as our environments are already part of the North Central AG.

For anyone interested, I migrated our Google OpenId Logins to Google OpenId Connect (OAuth2). thus far we have not had any issues with the endpoints.
