letsencrypt 与 nginx - 更新失败

自一个月以来，我收到了来自 letsencrypt 更新 cronjob 的错误。

  • 操作系统：Ubuntu 16.04.6 Xenial
  • letsencrypt 版本：certbot 0.23.0

  • Cronjob 命令：

    @daily letsencrypt renew >> /cronjobs/cert/daily-renew.log && /etc/init.d/nginx reload

错误信息：

Skipping.
All renewal attempts failed. The following certs could not be renewed:
  /etc/letsencrypt/live/website.domain.com/fullchain.pem (failure)

我尝试手动更新并检查是否有可用的更新。此外，我花了很多时间研究和测试来解决这个问题。所以我尝试了最后一步，为它创建了一个论坛帖子。

有人知道如何解决错误并更新我的证书吗？
