Let's Encrypt® 在 cPanel® 上使用 CloudFlare®

如果在網域上啟動 CloudFlare® CDN: Let’s Encrypt® will be unable to run and renew the SSL certificate on the cPanel® server. 這是有問題的, 特別是因為 Let’s Encrypt® 也會檢查 IPv6 記錄 (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.
