我在我的网站上使用 OpenID 已经有一段时间了，一切正常。但是，最近我在错误日志中看到了一些奇怪的错误。显然，对用户来说一切正常，他们可以登录。但是，在后台，OpenID 库似乎进入了导致一堆错误的循环。
此外，仅当我不在 localhost:3000 上访问时才会发生如果我通过我的 DynDns 名称隧道请求，我会收到错误消息。如果我来自 localhost:3000，什么都没有
底部是日志的片段。主要需要注意的是前几行：
未提供预先发现的信息 在 http://XXX.myopenid.com/ 上执行发现
这在初始 OpenID 请求之后的几秒钟内出现，并立即导致以下错误和堆栈跟踪。这会持续几次，然后停止。
有谁知道怎么回事？
