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.

https://check-your-website.server-daten.de/?q=cqkty.com 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.
