the rating is A, not A+, does that mean it is less secure? why only A? how to fix?
i did auto renew by run the following commands:
sudo crontab -eand include the content
30 2 * * 1 /usr/bin/letsencrypt renew >> /var/log/le-renew.log
but auto renew doesn’t work. Is that because it doesn’t auto restart my web server?
if so, can i do the following to fix it:
certbot renew --pre-hook "service nginx stop" --post-hook "service nginx start"
certbot certonly -n -d example.com -d www.example.com
