Có vẻ như có sự cố với DNS trên máy chủ cụ thể đó. Bạn có thể thử chạy lệnh sau:

$ /usr/local/cpanel/3rdparty/bin/perl -MCpanel::DnsRoots -MData::Dumper -e 'print Dumper(Cpanel::DnsRoots->new()->get_nameservers_for_domain("domain.com"));'

Chỉ cần thay thế "domain.com" bằng tên miền thực mà bạn đang muốn cài đặt SSL Let's Encrypt và xem liệu điều đó có trả về nameservers chính xác cho miền của bạn hay không.

Nếu chưa đúng thì đổi lại nameservers cho tên miền của bạn trong DNS Zone Manager và sau đó bạn thử cài lại SSL Let's Encrypt.
