DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "rkgam63l8k6g72u3sv8ghgj1se9s6061" between the hashed NSEC3-owner "rkga9drp1cmqci8fnh85armu4dndqtpm" and the hashed NextOwner "rkganqf9ei1s1kv2e0caltlqb8ja706v". 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 "ck0q2d6ni4i7eqh8na30ns61o48ul8g5". So that domain name is the Closest Encloser of "vpaulo.com". Opt-Out: True.

7. Comments


1. General Results, most used to calculate the result

Aname "monitor.vpaulo.com" is subdomain, public suffix is ".com", top-level-domain is ".com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .com-domains preloaded: 89449 (complete: 231048)
AGood: All ip addresses are public addresses
Warning: Only one ip address found: monitor.vpaulo.com has only one ip address.
Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: monitor.vpaulo.com has no ipv6 address.
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: one preferred version: non-www is preferred
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):1 complete Content-Type - header (3 urls)
https://monitor.vpaulo.com/ 192.254.69.114

HFatal error: http result with http-status 200, no encryption. Add a redirect http ⇒ https, so every connection is secure. Perhaps in your port 80 vHost something like "RewriteEngine on" + "RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]" (two rows, without the "). Don't add this in your port 443 vHost, that would create a loop.

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 the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain monitor.vpaulo.com, 1 ip addresses, 1 different http results.

AInfo:: 26 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
AInfo:: 26 Queries complete, 26 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Bad (greater 8):: An average of 13.0 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 2 different Name Servers found: ns19.domaincontrol.com, ns20.domaincontrol.com, 2 Name Servers included in Delegation: ns19.domaincontrol.com, ns20.domaincontrol.com, 2 Name Servers included in 1 Zone definitions: ns19.domaincontrol.com, ns20.domaincontrol.com, 1 Name Servers listed in SOA.Primary: ns19.domaincontrol.com.
AGood: Only one SOA.Primary Name Server found.: ns19.domaincontrol.com.
AGood: SOA.Primary Name Server included in the delegation set.: ns19.domaincontrol.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: ns19.domaincontrol.com, ns20.domaincontrol.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: domaincontrol.com
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): 173., 97., 2 different subnets (first two Bytes): 173.201., 97.74., 2 different subnets (first three Bytes): 173.201.77., 97.74.109.
AExcellent: Every Name Server IPv4-address starts with an unique Byte.
AInfo: IPv6-Subnet-list: 2 Name Servers with IPv6, 1 different subnets (first block): 2603:, 1 different subnets (first two blocks): 2603:0005:, 2 different subnets (first three blocks): 2603:0005:21d0:, 2603:0005:22d0:, 2 different subnets (first four blocks): 2603:0005:21d0:0000:, 2603:0005:22d0:0000:
AGood: Name Server IPv6 addresses from different subnets found.
AGood: Nameserver supports TCP connections: 2 good Nameserver
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): 2 good Nameserver
Nameserver doesn't pass all EDNS-Checks: ns19.domaincontrol.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.
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

Fatal: All checks of /.well-known/acme-challenge/random-filename have a redirect, destination doesn't have the random filename. 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 result with status 200 supports GZip.
https://monitor.vpaulo.com/ 192.254.69.114
200

Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
https://192.254.69.114/ 192.254.69.114

Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
https://monitor.vpaulo.com/ 192.254.69.114
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://192.254.69.114/ 192.254.69.114

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 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
