I want certificates on a number of subdomains -
I originally created one certificate will all the domains in the single certificate. but eventually some of the sites in that certificate were deleted/moved to a different server. So that caused problems when renewing the certificate as some of the domains failed for the DNS challange, and I could not renew any certificates.
So I started creating certificates separately for each site and that has hit rate limit and I can no longer issue new certificates (until next few days)
So what is the best strategy for issuing and renewing certificates without hitting the rate limit and also not being affected if I delete any sites.
