You have an existing certificate that contains a portion of the domains you
requested (ref: /etc/letsencrypt/renewal/domain.com.conf)

It contains these names: domain.com, www.domain.com

You requested these names for the new certificate: domain.com,
playground.domain.com, www.playground.domain.com, www.domain.com.

Do you want to expand and replace this existing certificate with the new
certificate?

An unexpected error occurred:
ValueError: Unable to set value to path!
Please see the logfiles in /var/log/letsencrypt for more details.

IMPORTANT NOTES:
 - Unable to install the certificate
 - Congratulations! Your certificate and chain have been saved at /etc/letsencrypt/live/domain.com/fullchain.pem
   Your key file has been saved at: /etc/letsencrypt/live/domain.com/privkey.pem
   Your cert will expire on 2019-07-19.
   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"
 - Some rewrite rules copied from /etc/apache2/sites-enabled/000-default.conf were disabled in the vhost for your HTTPS site located at /etc/apache2/sites-enabled/000-default-le-ssl.conf because they have the potential to create redirection loops.
