0 DS RR in the parent zone found



DS-Query in the parent zone has a valid NSEC RR as result with the domain name between the NSEC-Owner "om" and the NextOwner "omega". So the parent zone confirmes the non-existence of a DS RR.

DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "g2ldqdj30kafb771eie4vc0ftqh4apjf" between the hashed NSEC3-owner "g2hsa6fkqoldp161snm7064tmdi93qhd" and the hashed NextOwner "g3ci6mu4vi1ns64bqru7ieukh1akuu2c". So the parent zone confirmes the not-existence of a DS RR.

1. General Results, most used to calculate the result

Aname "cursos.colabioclic.om" is subdomain, public suffix is "om", top-level-domain-type is "country-code", Country is Oman, tld-manager is "Telecommunications Regulatory Authority (TRA)"
Agood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.

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

Info: Creating a Letsencrypt certificate with that domain name isn't possible. To create a certificate you need a registered, worldwide unique domain name. The domain name ends with a public suffix, that's good (not Grade Z). But the domain isn't registered. If you want a certificate with that domain name, you have to proof that you are the domain owner. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
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
