Nginx ClientError:（<；Response[500]>；，反序列化错误（&x27；以下字段为必填字段：detail&&x27；，））

我正在使用为两个站点创建自己的SSL证书

我正在Ubuntu 16.0.4 LTS上运行nginx版本：nginx/1.10.0

我运行以下命令：

me@yourbox:~$ sudo letsencrypt certonly --webroot -w /path/to/www/foo -d foo.com\
-d www.foo.com -w /path/to/www/foobar -d foobar.com -d www.foobar.com

输入电子邮件地址后，我收到以下错误消息：

An unexpected error occurred: `ClientError: (<Response [500]>,
DeserializationError('The following field are required: detail',))
Please see the logfiles in /var/log/letsencrypt for more details.`

发生意外错误：`ClientError:（，
反序列化错误（'需要以下字段：详细信息'，））
有关更多详细信息，请参阅/var/log/letsencrypt中的日志文件`

我觉得记录的消息对解释如何解决问题没有多大帮助。是否有人真正了解发生了什么？更重要的是，如何解决这个问题？

这个响应[500]意味着Let's Encrypt服务器响应API请求时出现500内部服务器错误。这是由于Let's Encrypt的后端出现错误造成的。只需等待片刻并重播请求，最终它就会成功

您可以在查看“让我们加密”服务状态。

他们已经知道这一点=>
