Upon the attempt to install or renew Let's Encrypt, Plesk returns the following error message:
PLESK_ERROR: Error: Could not issue a Let's Encrypt SSL/TLS certificate for example.com.
The "Certificates per Registered Domain" rate limit has been exceeded for example.com. Let's Encrypt allows no more than 20 certificates to be issued per registered domain, per week.
Rate limit of certificates that can be issued for a domain per week exceeded 20, so the certificate issuing was temporarily banned.
There is no way to reset or override the ban. You’ll need to wait until the rate limit expires after a week.
For example, if 10 certificates were issued on Tuesday and 10 more certificates on Friday, another 10 attempts can be performed again starting the next Tuesday.
