我有以下问题：我在 C# 上开发了 OpenID 身份验证系统，它在我的 LocalHost 上运行良好，但是当我发布它时，我不断收到此错误消息，我该怎么办？谢谢！

【问题讨论】：

发现有问题。您确定它可以连接到身份网址吗？（可能会导致问题，例如，如果您使用 http://localhost/openid 作为标识符，而 RP 位于 localhost 以外的其他位置）仅凭您提供的数据无法告诉您更多信息。
嗯，它只使用 Google、Yahoo、Chi.mp 和 MyOpenID 作为标识符。我没有使用 localhost 作为标识符。我的代码如下： //要求登录，或停止使用。 openIDLogin.LoggedIn += new EventHandler(openIDLogin_LoggedIn);

【解决方案1】：

Turn on logging 看看他们告诉你什么。

这通常是因为您的生产服务器有一个保护措施（防火墙、代理等）来阻止传出的 HTTP 请求，这当然是 OpenID 需要的。
