0 DS RR in the parent zone found



DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "pvi8fjgeo2ml8qccg63sd1i4b5k791cq" between the hashed NSEC3-owner "pvfo9btrnu8hcibv9lgej9lunirjd8u5" and the hashed NextOwner "pviql20393t1rhfqvj3hiojj3kp7aurr". So the parent zone confirmes the not-existence of a DS RR.

DS-Query in the parent zone sends valid NSEC3 RR with the Hash "lssonopupkrf65lob0e0isitat1f1dso" as Owner. That's the Hash of "com.ua" with the NextHashedOwnerName "lsuje1rih8764tjq5dqtkgg4psjv24eq". So that domain name is the Closest Encloser of "adelina.com.ua". Opt-Out: True.

1. General Results, most used to calculate the result

Aname "vpn-agents.adelina.com.ua" is subdomain, public suffix is ".com.ua", top-level-domain is ".ua", top-level-domain-type is "country-code", Country is Ukraine, tld-manager is "Hostmaster Ltd.", num .ua-domains preloaded: 514 (complete: 168171)
Agood: All ip addresses are public addresses
Warning: Only one ip address found: vpn-agents.adelina.com.ua 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: vpn-agents.adelina.com.ua has no ipv6 address.
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):0 complete Content-Type - header (4 urls)

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.

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.

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. 2 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, 2 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: All img-elements have a valid alt-attribute.: 2 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
