DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "d28j1lrufev75fluvrc931vak8r37g4m" between the hashed NSEC3-owner "d27fmkm9sp3jld38d65p9d0r9gbbh4i9" and the hashed NextOwner "d28v3c52bjao9ioh4sh652keq0dqg6ic". So the parent zone confirmes the not-existence of a DS RR.

CError - no preferred version www or non-www. Select one version as preferred version, then add a redirect https + not-preferred version to https + preferred version. Perhaps in your port 443 vHost something like "RewriteEngine on" + "RewriteCond %{SERVER_NAME} = example.com" + "ReWriteRule ^ https://www.example.com%{REQUEST_URI} [END,QSA,R=permanent]" (three rows, without the "). That should create a redirect https + example.com ⇒ https + www.example.com. Or switch both values to use the non-www version as your preferred version.
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.

3. DNS- and NameServer - Checks

AInfo:: 16 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 5 Name Servers.
AInfo:: 16 Queries complete, 16 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Ok (4 - 8):: An average of 3.2 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 5 different Name Servers found: ns3-l2.nic.ru, ns4-cloud.nic.ru, ns4-l2.nic.ru, ns8-cloud.nic.ru, ns8-l2.nic.ru, 5 Name Servers included in Delegation: ns3-l2.nic.RU, ns4-cloud.nic.RU, ns4-l2.nic.RU, ns8-cloud.nic.RU, ns8-l2.nic.RU, 5 Name Servers included in 1 Zone definitions: ns3-l2.nic.ru, ns4-cloud.nic.ru, ns4-l2.nic.ru, ns8-cloud.nic.ru, ns8-l2.nic.ru, 1 Name Servers listed in SOA.Primary: ns3-l2.nic.ru.
AGood: Only one SOA.Primary Name Server found.: ns3-l2.nic.ru.
AGood: SOA.Primary Name Server included in the delegation set.: ns3-l2.nic.ru.
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: ns3-l2.nic.ru, ns4-cloud.nic.ru, ns4-l2.nic.ru, ns8-cloud.nic.ru, ns8-l2.nic.ru
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: 5 different Name Servers found
Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 5 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.: 5 Name Servers, 1 Top Level Domain: ru
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: nic.ru
Warning: All Name Servers from the same Country / IP location.: 5 Name Servers, 1 Countries: RU
AInfo: Ipv4-Subnet-list: 15 Name Servers, 3 different subnets (first Byte): 193., 89., 91., 3 different subnets (first two Bytes): 193.232., 89.104., 91.217., 5 different subnets (first three Bytes): 193.232.146., 89.104.93., 89.104.95., 91.217.20., 91.217.21.
AGood: Name Server IPv4-addresses from different subnet found:
AGood: Nameserver supports TCP connections: 1 good Nameserver
AGood: Nameserver supports Echo Capitalization: 1 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 1 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 1 good Nameserver
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.

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status between 400 and 499, but not 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.

Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 2 script elements without defer/async.

AGood: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 6 external CSS / JavaScript files found
AGood: All CSS / JavaScript files are sent with a long Cache-Control header (minimum 7 days). So the browser can re-use these files, no download is required. 6 external CSS / JavaScript files with long Cache-Control max-age found
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
