DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "soj18v178igls77hvrua44dfmfd3n4rm" between the hashed NSEC3-owner "sohbu4npmieg52hh4snmlebujp6dqo60" and the hashed NextOwner "soortkdaqrvchop16q6jv1ac4ig6m8n2". So the parent zone confirmes the not-existence of a DS RR.

1. General Results, most used to calculate the result

Aname "certix.io" is domain, public suffix is "io", top-level-domain-type is "country-code", Country is British Indian Ocean Territory (the), tld-manager is "IO Top Level Domain Registry"
Agood: All ip addresses are public addresses
Warning: Only one ip address found: certix.io has only one ip address.
Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: certix.io has no ipv6 address.
Agood: No asked Authoritative Name Server had a timeout
Agood: destination is https
Agood - only one version with Http-Status 200
Agood: one preferred version: non-www is preferred
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
Ahttp://certix.io/ 18.191.109.244

Misconfiguration - main pages should never send http status 400 - 499
Nhttps://18.191.109.244/ 18.191.109.244

Error - Certificate isn't trusted, RemoteCertificateNameMismatch, RemoteCertificateChainErrors
XFatal: Wrong CNAME definition found.Domain name: www.certix.io, CNAME: 18.191.109.244: IPv4 address found, but not allowed. Only domain names are allowed.
Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain certix.io, 1 ip addresses.

2. DNS- and NameServer - Checks

AInfo:: 16 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
AInfo:: 16 Queries complete, 16 with IPv6, 0 with IPv4.

AGood: Only one SOA.Primary Name Server found.: ns-1667.awsdns-16.co.uk.
AGood: SOA.Primary Name Server included in the delegation set.: ns-1667.awsdns-16.co.uk.
AGood: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: ns-1456.awsdns-54.org, ns-1667.awsdns-16.co.uk, ns-399.awsdns-49.com, ns-875.awsdns-45.net
AGood: All Name Server Domain Names have a Public Suffix.
AGood: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
AGood: All Name Server ip addresses are public.
AGood: Minimal 2 different name servers (public suffix and public ip address) found: 4 different Name Servers found
AGood: All name servers have ipv4- and ipv6-addresses.: 4 different Name Servers found
AGood: Name servers with different Top Level Domains / Public Suffix List entries found: 4 Name Servers, 4 Top Level Domains: org, net, com, co.uk
AGood: Name Servers with different domain names found.: 4 different Domains found
Warning: All Name Servers from the same Country / IP location.: 4 Name Servers, 1 Countries: US
AInfo: Ipv4-Subnet-list: 4 Name Servers, 1 different subnets (first Byte): 205., 1 different subnets (first two Bytes): 205.251., 4 different subnets (first three Bytes): 205.251.193., 205.251.195., 205.251.197., 205.251.198.

AGood: All SOA have the same Serial Number
Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.

3. Content- and Performance-critical Checks

AGood: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: No https + http status 200 with inline CSS / JavaScript found
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
https://certix.io/ 18.191.109.244
200

Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 1 image files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 1 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: All img-elements have a valid alt-attribute.: 1 img-elements found.
AGood: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
