Let’s Encrypt® on cPanel® s CloudFlare®

Pokud je v doméně aktivován CloudFlare® CDN: Let’s Encrypt® will be unable to run and renew the SSL certificate on the cPanel® server. To je problematické, zejména proto, že Let’s Encrypt® kontroluje i záznam IPv6 (and is not able to verify the domain if the server has no IPv6). However there is a simple solution: within CloudFlare® the real NS servers needs to be assigned to the following subdomains:

• _acme-challenge
• _cpanel-dcv-test-record

The DNS records will then rely on the cPanel® real NS servers.
