	DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "i97fh8stbfh18svbtsi7q4v2d8cm4816" between the hashed NSEC3-owner "i968idpl9edjipturdvlfm01sai1cabk" and the hashed NextOwner "ia6gjtmqp6kt3sgh398t6dhr7u3hggl4".

	1. General Results, most used to calculate the result
A	name "app.hubin.ie" is subdomain, public suffix is ".ie", top-level-domain is ".ie", top-level-domain-type is "country-code", Country is Ireland, tld-manager is "University College Dublin Computing Services Computer Centre", num .ie-domains preloaded: 407 (complete: 276475)
A	Good: No asked Authoritative Name Server had a timeout
A	DNS: "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.
B	No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.app.hubin.ie

A	Good: 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
	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.
A	Good: 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
