今天收到了Let’s Encrypt的邮件，大意就是以后不支持TLS-SNI-01，需要替换为其他校验方式。
You need to update your ACME client to use an alternative validation method (HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate renewals will break and existing certificates will start to expire.
参考官方的教程，开始进行升级。首先将certbot升级到0.28.0
ubuntu@ip-172-31-12-237:~$ certbot --version certbot 0.19.0
然后按步骤升级，dry-run通过

然后强制更新
