acme.sh, the ACME client discussed in the README, has changed to obtain ECC certificates from Let's Encrypt by default. With that change, it has changed the default directory for the certificate files from /root/.acme.sh/$DOMAIN/ to /root/.acme.sh/$DOMAIN_ecc/, which will cause this script to fail. The solution for the time being is to correctly set privkey_path and fullchain_path in the config file.
