DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "stfj4bc2v554o3n3pifr6qrve11o50hd" between the hashed NSEC3-owner "stfbllkellc8t5g1qnh3gem1hlqvjt64" and the hashed NextOwner "stfu7qnbgr3q1prmt4op7usoki3nfgue". So the parent zone confirmes the not-existence of a DS RR.

7. Comments


1. General Results, most used to calculate the result

Aname "webserver01.alekzakh.info" is subdomain, public suffix is ".info", top-level-domain is ".info", top-level-domain-type is "generic", tld-manager is "Afilias Limited", num .info-domains preloaded: 906 (complete: 128404)
Agood: All ip addresses are public addresses
Warning: Only one ip address found: webserver01.alekzakh.info 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: webserver01.alekzakh.info has no ipv6 address.
Agood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
Agood: one preferred version: non-www is preferred
AGood: No cookie sent via http.
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: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):1 complete Content-Type - header (4 urls)

Url with incomplete Content-Type - header - missing charset
Bhttps://webserver01.alekzakh.info/ 13.95.143.121
200

Missing HSTS-Header
CError - more then one version with Http-Status 200. After all redirects, all users (and search engines) should see the same https url: Non-www or www, but not both with http status 200.
HFatal error: http result with http-status 200, no encryption. Add a redirect http ⇒ https, so every connection is secure. Perhaps in your port 80 vHost something like "RewriteEngine on" + "RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]" (two rows, without the "). Don't add this in your port 443 vHost, that would create a loop.
Mhttps://13.95.143.121/ 13.95.143.121
404

Misconfiguration - main pages should never send http status 400 - 499
Nhttps://13.95.143.121/ 13.95.143.121
404

Error - Certificate isn't trusted, RemoteCertificateNameMismatch
OOld connection: CBC Cipher suites are deprecated. A GCM Cipher suite is required. See the Chrome-Check-Result:: obsolete connection settings. The connection to this site is encrypted and authenticated using TLS 1.2, ECDHE_RSA with P-256, and AES_256_CBC with HMAC-SHA1.
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 the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain webserver01.alekzakh.info, 1 ip addresses, 1 different http results.

2. DNS- and NameServer - Checks

AInfo:: 27 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
AInfo:: 27 Queries complete, 27 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Bad (greater 8):: An average of 13.5 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 2 different Name Servers found: ns27.domaincontrol.com, ns28.domaincontrol.com, 2 Name Servers included in Delegation: ns27.domaincontrol.com, ns28.domaincontrol.com, 2 Name Servers included in 1 Zone definitions: ns27.domaincontrol.com, ns28.domaincontrol.com, 1 Name Servers listed in SOA.Primary: ns27.domaincontrol.com.
AGood: Only one SOA.Primary Name Server found.: ns27.domaincontrol.com.
AGood: SOA.Primary Name Server included in the delegation set.: ns27.domaincontrol.com.
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: ns27.domaincontrol.com, ns28.domaincontrol.com
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: 2 different Name Servers found
AGood: All name servers have ipv4- and ipv6-addresses.: 2 different Name Servers found
Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 2 Name Servers, 1 Top Level Domain: com
Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: domaincontrol.com
Warning: All Name Servers from the same Country / IP location.: 2 Name Servers, 1 Countries: US
AInfo: Ipv4-Subnet-list: 2 Name Servers, 2 different subnets (first Byte): 173., 97., 2 different subnets (first two Bytes): 173.201., 97.74., 2 different subnets (first three Bytes): 173.201.71., 97.74.103.

Nameserver doesn't pass all EDNS-Checks: ns27.domaincontrol.com: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
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://webserver01.alekzakh.info/ 13.95.143.121
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.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AInfo: No img element found, no alt attribute checked
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
