DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "nf1ok0a8m1qccc5k9met3abm0kliec65" between the hashed NSEC3-owner "nf1ogd1l9nvcne3j3gte4t7aaj9uqrfa" and the hashed NextOwner "nf1pc67kk04602didgoa63d43kgl89rl". 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 "k5u3v0fise3o6ht90mhg2usjbf5qpoa2" as Owner. That's the Hash of "com.br" with the NextHashedOwnerName "k5u4m4qo1s2228g69oe2ha3cegvk5qr0". So that domain name is the Closest Encloser of "delpeloso.com.br". Opt-Out: True.

1. General Results, most used to calculate the result

Aname "delpeloso.com.br" is domain, public suffix is ".com.br", top-level-domain is ".br", top-level-domain-type is "country-code", Country is Brazil, tld-manager is "Comite Gestor da Internet no Brasil", num .br-domains preloaded: 2066 (complete: 168171)
Agood: All ip addresses are public addresses
AGood: Minimal 2 ip addresses per domain name found: www.delpeloso.com.br has 2 different ip addresses (authoritative).
AGood: Ipv4 and Ipv6 addresses per domain name found: www.delpeloso.com.br has 1 ipv4, 1 ipv6 addresses
Warning: Only one ip address found: delpeloso.com.br 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: delpeloso.com.br has no ipv6 address.
Agood: No asked Authoritative Name Server had a timeout
AGood: No cookie sent via http.
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
CError - no version with Http-Status 200

302
https://delpeloso.com.br/
Wrong redirect one domain http to other domain https. First redirect to https without new dns query, so the server can send the HSTS header. That's fundamental using HSTS (Http Strict Transport Security). First step: Add correct redirects http ⇒ https. 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. Then recheck your domain, should be Grade C. There is the rule to select one https version as preferred version.

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

Fatal: Check of /.well-known/acme-challenge/random-filename is blocked, http connection error. Creating a Letsencrypt certificate via http-01 challenge can't work. You need a running webserver (http) and an open port 80. If it's a home server + ipv4, perhaps a correct port forwarding port 80 extern ⇒ working port intern is required. Port 80 / http can redirect to another domain port 80 or port 443, but not other ports. If it's a home server, perhaps your ISP blocks port 80. Then you may use the dns-01 challenge. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

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
