I am requesting a single certificate for multiple domains (there are 15 total - they’re basically
ourplatform.clientswebsite.com so it’s not like they’re all from the same domain). Our app runs on Heroku, so I use a tool called sabayon which manages setting up the
http-01 token/key pairs on a Heroku app automatically and then grabbing the certificate if/when all is good.
I have been able to issue and renew the certificate no problem several times now, but this last renewal is problematic. The cert expires on March 3rd, so I don’t have a lot of time to work with here.
Basically, I get a unique
https://acme-v01.api.letsencrypt.org/acme/authz/:token for 11 of the 15 domains as expected. If I look at any of the
authz/:token in my browser I see that there are 3 challenges, one of each -
dns-01. They are all pending and do not go beyond that state.
My server does not get queried for the token/key pair.
So I guess I get a 429 after 11 of these? Could someone explain why? I was under the impression that I could request a 100 of these?
