Yes, it looks like when I initially set this up, I only did it for 2 domains, but when I finished I decided on using the same certificate for 3 domains.
so initially created a certificate for
roojs.com www.roojs.com
Then later on changed it to
roojs.com www.roojs.com master.roojs.com
I would agree with you, trying to handle this or similar situations is a bit of a can of worms, so probably not worth changing anything (the only result of it is that I get an extra email once… - not really a issue)
It may be worth adding some notes to the automated email
- getting this email, but have already renewed? Let’sencrypt tracks set’s of domains, if you subsequently created a certificate with a different set of domains, then just ignore this message.
