DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "6tuh0gtjmeu8rueed114rkrenquoed40" between the hashed NSEC3-owner "6tudcfrknr572i5c0uc4sacr7a29acu9" and the hashed NextOwner "6tulfboa2428tkutfu787kbl9urp7h08". So the parent zone confirmes the not-existence of a DS RR.

AGood: More then one ip address per domain name found, checking all ip addresses the same http status and the same certificate found: Domain letsencrypt.org, 2 ip addresses.
AGood: More then one ip address per domain name found, checking all ip addresses the same http status and the same certificate found: Domain www.letsencrypt.org, 2 ip addresses.
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 different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain letsencrypt.org, 2 ip addresses.

Both certificates are different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain www.letsencrypt.org, 2 ip addresses.

2. DNS- and NameServer - Checks

AInfo:: 2 different Name Servers found: owen.ns.cloudflare.com, vera.ns.cloudflare.com, 2 Name Servers included in Delegation: owen.ns.cloudflare.com, vera.ns.cloudflare.com, 2 Name Servers included in 1 Zone definitions: owen.ns.cloudflare.com, vera.ns.cloudflare.com, 1 Name Servers listed in SOA.Primary: owen.ns.cloudflare.com.
AGood: Only one SOA.Primary Name Server found.: owen.ns.cloudflare.com.
AGood: SOA.Primary Name Server included in the delegation set.: owen.ns.cloudflare.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: owen.ns.cloudflare.com, vera.ns.cloudflare.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: cloudflare.com
Warning: All Name Servers from the same Country / IP location.: 2 Name Servers, 1 Countries: US
AInfo: Ipv4-Subnet-list: 2 Name Servers, 1 different subnets (first Byte): 173., 1 different subnets (first two Bytes): 173.245., 2 different subnets (first three Bytes): 173.245.58., 173.245.59.
AGood: Name Server IPv4-addresses from different subnet found:
AInfo: IPv6-Subnet-list: 2 Name Servers with IPv6, 1 different subnets (first block): 2606:, 1 different subnets (first two blocks): 2606:4700:, 2 different subnets (first three blocks): 2606:4700:0050:, 2606:4700:0058:, 2 different subnets (first four blocks): 2606:4700:0050:0000:, 2606:4700:0058:0000:
AGood: Name Server IPv6 addresses from different subnets found.
AGood: Nameserver supports TCP connections: 4 good Nameserver
AGood: Nameserver supports Echo Capitalization: 4 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 4 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.

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: Every https result with status 200 supports GZip.
AGood: No https + http status 200 with inline CSS / JavaScript found
https://letsencrypt.org/ 165.22.65.139
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
https://letsencrypt.org/ 165.227.0.164
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
https://letsencrypt.org/ 2604:a880:2:d0::ddf:c001
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: All CSS / JavaScript files are sent with GZip. That reduces the content of the files. 20 external CSS / JavaScript files found
AGood: All images with internal compression not sent via GZip. Images (.png, .jpg) are already compressed, so an additional GZip isn't helpful. 254 images (type image/png, image/jpg) found without additional GZip. Not required because these images are already compressed
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 20 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 20 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 image files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 258 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 258 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: Some img-elements have a valid alt-attribute.: 258 img-elements found, 254 img-elements with correct alt-attributes (defined, not an empty value).
Wrong: img-elements without alt-attribute or empty alt-attribute found. The alt-attribute ("alternative") is required and should describe the img. So Screenreader and search engines are able to use these informations.: 4 img-elements without alt-attribute, 0 img-elements with empty alt-attribute 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
