CNAME-Query sends a valid NSEC3 RR as result with the hashed query name "7ob0hgr9b0g18eug1bts4kj8g5h9orao" equal the hashed NSEC3-owner "7ob0hgr9b0g18eug1bts4kj8g5h9orao" and the hashed NextOwner "88ci48k98e05qpk8vgs0cj9krqvpum9q". So the zone confirmes the not-existence of that CNAME RR, but the existence of that query name (minimal one RR with that name exists).

A

Good: default-src directive only with 'none' or 'self', additional sources are blocked.
A

Good: default-src without 'unsafe-inline' or 'unsave-eval'.
A

Good: form-action directive found. That reduces the risk sending data to unwanted domains. form-action is a navigation-directive, so default-src isn't used.
A

Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
A

Good: base-uri directive found. That limits the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
A

Good: No object-src found, but the default-src used as fallback is defined and restricted.

3. DNS- and NameServer - Checks

AInfo:: 12 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 3 Name Servers.
AInfo:: 12 Queries complete, 12 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Ok (4 - 8):: An average of 4.0 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 3 different Name Servers found: root-dns.netcup.net, second-dns.netcup.net, third-dns.netcup.net, 3 Name Servers included in Delegation: root-dns.netcup.net, second-dns.netcup.net, third-dns.netcup.net, 3 Name Servers included in 1 Zone definitions: root-dns.netcup.net, second-dns.netcup.net, third-dns.netcup.net, 1 Name Servers listed in SOA.Primary: root-dns.netcup.net.
AGood: Only one SOA.Primary Name Server found.: root-dns.netcup.net.
AGood: SOA.Primary Name Server included in the delegation set.: root-dns.netcup.net.
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: root-dns.netcup.net, second-dns.netcup.net, third-dns.netcup.net
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: 3 different Name Servers found
AGood: All name servers have ipv4- and ipv6-addresses.: 3 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.: 3 Name Servers, 1 Top Level Domain: net
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: netcup.net
Warning: All Name Servers from the same Country / IP location.: 3 Name Servers, 1 Countries: DE
AInfo: Ipv4-Subnet-list: 3 Name Servers, 3 different subnets (first Byte): 188., 37., 46., 3 different subnets (first two Bytes): 188.68., 37.221., 46.38., 3 different subnets (first three Bytes): 188.68.63., 37.221.199., 46.38.225.

AGood: Nameserver supports Echo Capitalization: 6 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 6 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 6 good Nameserver
AGood: All SOA have the same Serial Number
AGood: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates

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.
AGood: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 2 external CSS / JavaScript files found
AGood: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 16 images (type image/png, image/jpg, image/jpeg, image/webp, image/gif) found without additional Compression. Not required because these images are already compressed
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. 2 external CSS / JavaScript files with long Cache-Control max-age found
AGood: All images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 16 image files with long Cache-Control max-age found
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: All img-elements have a valid alt-attribute.: 16 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
