谷歌的OpenID：没有OpenID端点发现（间断） [英] Google OpenId: No OpenID endpoint found (intermittent)

问题描述

通常使用谷歌的OpenID工作正常，上千次，那么它就会开始间歇性脚麻超时一个小时左右（某些请求将验证但不是全部）。反复验证，最终工作。

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.

错误信息是：

Event code: 200000 
Event message: No OpenID endpoint found. : https://www.google.com/accounts/o8/id 

Sequence contains no elements

添加在log4net的收益率：

Adding in log4net yields:

DotNetOpenAuth.Yadis:
Error while performing discovery on: "https://www.google.com/accounts/o8/id": 
DotNetOpenAuth.Messaging.ProtocolException:

和

DotNetOpenAuth.Http WebException: 
 Timeout from https://www.google.com/accounts/o8/id, no response available.

任何想法？

推荐答案

这听起来像你需要修复您的网络延迟。这似乎不太可能，谷歌将成为瓶颈在这里。

It sounds like you need to fix your network latency. It seems highly unlikely that Google would be the bottleneck here.

您可能还需要增加对你们地区的HTTP超时，减少故障率。全套选项可以 rel=\"nofollow\">。具体来说，你很可能在寻找：

You may also want to increase the HTTP timeouts on your end to reduce the failure rate. The full set of options is available here. Specifically you're probably looking for:

<untrustedWebRequest
            timeout="00:00:10"
            readWriteTimeout="00:00:01.500" />
