So the first part of the instructions is no longer relevant since version 0.22 of certbot. However the plugins portion mentions Cloudflare and I’m using Bluehost. I’m really not sure how to proceed. Is there a Bluehost Plugin? Is there something I can do manually on the Bluehost record to add domain authentication?
In order to use Certbot to get a wildcard certificate, you should have an API for your DNS provider. Is Bluehost your DNS provider? Does it offer an API?
If not, there’s also a trick you can use with a CNAME record in order to use a different DNS provider to complete the challenges.
