• domain listing
  • e.g. htyp.org

Files

• /etc/letsencrypt/
  • +archive/ - contains one folder per domain
    • +<domain folder>/ -- folder names are arbitrary, specified in renewal/ files
  • +live/
    • +<domain name> - contains links to the current files
  • +renewal/ - contains configurations to load (equivalent to sites-enabled/ in Apache/Nginx)

I'm guessing that LE adds a new fileset to archive/<domain folder>/ for each renewal, and updates the links in live/<domain name>.

Errors

• Error requesting challenges: Error creating new authz :: Validations for new domains are disabled in the V1 API
  • This is because of the End of Life Plan for ACMEv1
  • If you've been using Let's Encrypt via VirtualMin, you may have to actually install CertBot (apparently VirtualMin has its own method of handling renewals but will use CertBot if it is installed) - instructions here, but basically:
    • apt install socat certbot
    • certbot register

Links

• certificate lookup: replace htyp.org with any domain. Use %domain for wildcard matches.
