Hello folks, Although I have some technical proficiency my experience and understanding of SSL/TLS certificates leaves a lot to be desired and specifically how best to use the Let’s Encrypt service. I am a big fan of what you are trying to do and really want you to succeed. Now to my problem.
I have a domain (edlivered.net) that I was successfully able to get a certificate for using the letsencrypt-auto client. A few week after obtaining that certificate we added two more subdomains, i.e. demo1.edelivered.net and demo2.edelivered.net and when I tried to add those domains I guess I messed things up because now I’m getting the “There were too many requests of a given type :: Error creating new cert :: Too many certificates already issued” warning/ error. Now I certainly understand the need to limit requests, but I would like to understand better what happened. I tried to add the new subdomains to the certificate like so:
but I got the following error: Requested domain is not a FQDN
so after that I tried to add them separately but ran into other errors due to problems on my end and after messing everything up royally (on my end) I decided to start clean and deleted all the certificates I directories I currently had. When I tried again I started getting the "There were too many requests " error.
It is my understanding that I have to wait seven days before being able to try again and that’s fine. What I’m trying to understand is why I got the “Requested domain is not a FQDN” error and what is the recommended way to add subsequent subdomains to an existing domain certificate? I understand there is a limit to the number of subdomains on one certificate and believe that number is 100, is that correct?
Any help would be greatly appreciated.
