Hello,
Please see this article:
I suggest that you:
- Apply for a rate limit exemption from Let’s Encrypt.
- Submit the domain to the Public Suffix List , which is used by Let’s Encrypt, but also has broader implications for things like HTTP cookies in web browsers. (For example,
abc.europa.eu
wouldn’t be able to set a*.segmentocorporativo.com
cookie and hackxyz.segmentocorporativo.com
.)
It seems that you have too many currently pending authorizations.
