DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "7t2oi5c49ga8u53m7jdb9b3fqqqbuabk" between the hashed NSEC3-owner "7t1bivtifldgq3n2njnpt8iplq04gijb" and the hashed NextOwner "7t5osblsgm08b0onnm94rqhehtiv374q". 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 "j20c0qkdhua3cumnkst289ff06u2sq91" as Owner. That's the Hash of "ru" with the NextHashedOwnerName "j21lulr2unpa28sere28ovnjnj67qp7v". So that domain name is the Closest Encloser of "extrapost.ru". Opt-Out: True.

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
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: nameself.com
Warning: All Name Servers from the same Country / IP location.: 2 Name Servers, 1 Countries: RU
AInfo: Ipv4-Subnet-list: 4 Name Servers, 3 different subnets (first Byte): 87., 88., 95., 3 different subnets (first two Bytes): 87.242., 88.212., 95.213., 4 different subnets (first three Bytes): 87.242.73., 88.212.207., 88.212.208., 95.213.146.

AExcellent: Every Name Server IPv6-address starts with an unique Hex-block
AGood: Nameserver supports TCP connections: 3 good Nameserver
AGood: Nameserver supports Echo Capitalization: 3 good Nameserver
XNameserver Timeout checking Echo Capitalization: ns2.nameself.com / 2a02:2100:e001:4::203
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 3 good Nameserver
XNameserver Timeout checking EDNS512: ns2.nameself.com / 2a02:2100:e001:4::203
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 3 good Nameserver
Nameserver doesn't pass all EDNS-Checks: ns1.nameself.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.
Nameserver doesn't pass all EDNS-Checks: ns2.nameself.com / 2a02:2100:e001:4::203: OP100: fatal timeout. FLAGS: fatal timeout. V1: fatal timeout. V1OP100: fatal timeout. V1FLAGS: fatal timeout. DNSSEC: fatal timeout. V1DNSSEC: fatal timeout. NSID: fatal timeout. COOKIE: fatal timeout. CLIENTSUBNET: fatal timeout.
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.

4. 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: 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
