Let's EncryptのHTTPS更新について

今を遡ること３ヶ月前HTTPSの導入が必要になり、急遽Let's Encryptで導入しました。
そのときのログに

bash
1IMPORTANT NOTES:
2 - Congratulations! Your certificate and chain have been saved at:
3   /etc/letsencrypt/live/monkeytalk.jp/fullchain.pem
4   Your key file has been saved at:
5   /etc/letsencrypt/live/monkeytalk.jp/privkey.pem
6   Your cert will expire on 2019-02-19. To obtain a new or tweaked
7   version of this certificate in the future, simply run certbot-auto
8   again with the "certonly" option. To non-interactively renew *all*
9   of your certificates, run "certbot-auto renew"
10 - Your account credentials have been saved in your Certbot
11   configuration directory at /etc/letsencrypt. You should make a
12   secure backup of this folder now. This configuration directory will
13   also contain certificates and private keys obtained by Certbot so
14   making regular backups of this folder is ideal.
15 - If you like Certbot, please consider supporting our work by:

17   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
18   Donating to EFF:                    https://eff.org/donate-le

みたいなことが書いてありました。そこで今日これをするべく
certbot-auto renew
しました。
結果は
