我正在为两个站点创build自己的SSL证书，使用certbot和letencrypt 。
我在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 input我的电子邮件地址后，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.`
这里是/var/log/letsencrypt/letsencrypt.log的内容：

我没有findlogging的消息在解释如何解决这个问题非常有帮助。 有没有人真的明白发生了什么 – 更重要的是，如何解决这个问题？
这个响应[500]意味着让我们的加密服务器对500个内部服务器错误的API请求作出响应。 这是由于Let's Encrypt的后端方面的错误。 等待片刻，重播请求，最终成功。
您可以在http://letsencrypt.status.io/查看Let's Encrypt服务状态。
