Ultimamnte me di cuenta que al intentar certificar mis dominios certbot envia este error:
Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA.
Buscando en google encontre este articulo que lo que dice básicamente es que Let’s Encrypt ha desahabilitado (resientemente) el TLS-SNI-01 challenge por lo que se recomienda actualizar certbot a 0.21.0 o superior (que por ahora no esta viable :o) y una alternativa es usar certbot-auto que forza la ultima versión y pues estas son las intrucciones instalar y usar certbot-auto:

1.- Instalar certbot-auto

wget https://dl.eff.org/certbot-auto
chmod a+x ./certbot-auto
./certbot-auto --help

./certbot-auto --nginx -d example.com -d www.example.com --test-cert

b).- Para apache

./certbot-auto --apache -d example.com -d www.example.com --test-cert

Si al final obtines un resultado asi significa que si es posible certificar nuestro dominio.

Output

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/example.com/fullchain.pem. Your cert will
   expire on 2017-10-23. To obtain a new or tweaked version of this
   certificate in the future, simply run certbot again with the
   "certonly" option. To non-interactively renew *all* of your
   certificates, run "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate

Si todo sale como esperamos usamos –force-renew

./certbot-auto --nginx -d example.com -d www.example.com --force-renew

b).- Para apache

./certbot-auto --apache -d example.com -d www.example.com --force-renew
