Your certificate and chain have been saved at: /etc/letsencrypt/live/mail.diamondbaycondotelresort.vn/fullchain.pem Your key file has been saved at: /etc/letsencrypt/live/mail.diamondbaycondotelresort.vn/privkey.pem Your cert will expire on 2018-03-22. To obtain a new or tweaked version of this certificate in the future, simply run letsencrypt-auto again. To non-interactively renew all of your certificates, run “letsencrypt-auto renew”
But i use sslchecker (sslshopper.com) is not update, my ssl still expire
Certbot with the certonly option will renew the certificate, but it won’t apply it. You’ll need to follow the procedure for applying the new certificate to your server. Usually this simply requires reloading its configuration, assuming the renewed cert is in the same location as the old one (with Certbot, it ill be in most cases.)
Once you determine which command reloads your server, you can accomplish this automatically upon renewal by using the --renewal-hook or --post-hook flags.
