DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "cs81fq8403npqfm1at1np76s47apja64" between the hashed NSEC3-owner "cs81esje5aujubvpelef7o8n1c19hrti" and the hashed NextOwner "cs81fsg0u0jss5pi1s3o0sdd9q7d7t9j". 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 "ck0pojmg874ljref7efn8430qvit8bsm" as Owner. That's the Hash of "com" with the NextHashedOwnerName "ck0q1gin43n1arrc9osm6qpqr81h5m9a". So that domain name is the Closest Encloser of "linuxlighthouse.com". Opt-Out: True.

2. DNS- and NameServer - Checks

AInfo:: 7 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
AInfo:: 7 Queries complete, 3 with IPv6, 4 with IPv4.
Warning: Only some DNS Queries done via ipv6. IPv6 is the future, so the name servers of your name servers should have ipv6 addresses.
AGood: Some ip addresses of name servers found with the minimum of two DNS Queries. One to find the TLD-Zone, one to ask the TLD-Zone.ws.linuxlighthouse.com (108.220.213.121)
Ok (4 - 8):: An average of 3.5 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 2 different Name Servers found: ns2.swbell.net, ws.linuxlighthouse.com, 2 Name Servers included in Delegation: ns2.swbell.net, ws.linuxlighthouse.com, 2 Name Servers included in 2 Zone definitions: ns2.swbell.net, ws.linuxlighthouse.com, 1 Name Servers listed in SOA.Primary: ws.linuxlighthouse.com.
AGood: Only one SOA.Primary Name Server found.: ws.linuxlighthouse.com.
AGood: SOA.Primary Name Server included in the delegation set.: ws.linuxlighthouse.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
Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 2 different Name Servers found
AGood: Name servers with different Top Level Domains / Public Suffix List entries found: 2 Name Servers, 2 Top Level Domains: net, com
AGood: Name Servers with different domain names found.: 2 different Domains found
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): 108., 151., 2 different subnets (first two Bytes): 108.220., 151.164., 2 different subnets (first three Bytes): 108.220.213., 151.164.11.
AExcellent: Every Name Server IPv4-address starts with an unique Byte.
AInfo: Nameserver mit different domain names found. May be a problem with DNS-Updates
AGood: Nameserver supports Echo Capitalization: 2 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 2 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 1 good Nameserver
Nameserver doesn't pass all EDNS-Checks: ns2.swbell.net / 151.164.11.218: OP100: SOA expected, but NOT found, NOERR expectend and NOERR found, Version 0 expectend and found, no OPT100 expected, no OPT100 found. FLAGS: SOA expected, but NOT found, NOERR expectend and NOERR found, Version 0 expectend and found. V1: ok. V1OP100: ok. V1FLAGS: ok. DNSSEC: SOA expected, but NOT found, NOERR expectend and NOERR found, Version 0 expectend and found. V1DNSSEC: ok. NSID: SOA expected, but NOT found, NOERR expectend and NOERR found, Version 0 expectend and found. COOKIE: SOA expected, but NOT found, NOERR expectend and NOERR found, Version 0 expectend and found. CLIENTSUBNET: ok.
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://www.linuxlighthouse.com/ 108.220.213.121
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.

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
