Hi @patricelee

your nameservers are bad.

A name "cqkty.com" is domain, public suffix is "com"
A good: All ip addresses are public addresses
A good - only one version with Http-Status 200
H fatal error: No https - result with http-status 200, no encryption
H fatal error: http result with http-status 200, no encryption
X Fatal error: Nameserver doesn't support TCP connections. May be a problem ordering a Letsencrypt certificate.: 2 Nameserver without support
X Fatal error: Nameserver doesn't support echo capitalization: 1 Nameserver without support
X Nameserver Timeout checking Echo Capitalization: 1 Nameserver with timeout
X Fatal error: Nameserver doesn't support EDNS with max. 512 Byte Udp payload or sends more then 512 Bytes: 1 Nameserver without support
X Nameserver Timeout checking EDNS512: 1 Nameserver without support

They have timeouts, don't support TCP, random capitalization and EDNS.

cqkty.com - Make your website better - DNS, redirects, mixed content, certificates found an ip address. But only by querying the system nameservers (cached entries).

Is it possible that you change your nameservers?

Is there any NS in your favorite list ?

Normally, your domain registrar manages your nameservers and is the hoster of your webspace.

So it’s first a question of your hosting.
