Let's Encrypt fails to issue a certificate with the following error:
PLESK_ERROR: The example.com DNS zone contains an AAAA record, but the domain is not assigned an IPv6 address in Plesk.
To resolve the issue, either assign an IPv6 address to example.com ("Websites & Domains" > "Web Hosting Access") or remove the AAAA record from the domain.com DNS zone.
PLESK_ERROR: Your domain in Plesk is hosted on the IP address(es): 203.0.113.2 , but the DNS challenge used another IP address: 203.0.113.3.
Please check the actual DNS zone of your domain and make sure that the IP addresses in the DNS zone and for the hosting are the same.
A domain is behind CloudFlare DNS.
Automatic CloudFlare IPv6 Gate, that is preventing the certificate from creation.
To solve this issue and renew certificates on domains, where CloudFlare is used, please follow next steps:
Go the CloudFlare account, open Settings page at CloudFlare.com > My websites > Settings (drop-down menu) > CloudFlare settings and disable IPv6.
