Certbot autorenew失败

Question

今天，我有一个certbot autorenew失败。用于续订证书的cron脚本失败，并且证书过期。下面是日志，其中包括在最后我ssh'ing到框中手动运行certbot-auto renew --standalone --no-self-upgrade命令来解决问题。

我的问题是 - 这确实显示了证书更新错误的根源？它与今天的GitHub中断有关吗，还是另一个问题？我可以做些什么来避免这种情况呢？

这是一个运行更新脚本cron作业（LE-renew.log是下面的日志文件的名称）：

30 2 * * 1 /usr/local/sbin/certbot-auto renew >> /var/log/le-renew.log 

LE-renew.log：

的跳转出来给我最重要的事情是，你在这里的操作问题：

今天我不得不a certbot autorenew failure。用于续订 证书的cron脚本失败，和我的证书到期。

你为什么要等到最后一天可能续约？您可以每天运行certbot，并且它会续约在未来30天内过期的任何事情。这应该会给你更多的时间来诊断和应对单次发行失败。

你也应该监控为失败的cron作业。无论是通过外部服务，还是通过某种方式通知cron作业失败。也许试试here的答案。
