DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "72pl99u15s6hr4mtqlh9kgern7110bp5" between the hashed NSEC3-owner "72pk23ctp05jgotkl5rnc712k5jm154f" and the hashed NextOwner "72prrusgasd24ktf3le8niq4iql0n5vm". 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 "97iomm39jdqnuedfjpmusaj6ga11997n" as Owner. That's the Hash of "sk" with the NextHashedOwnerName "97ippbal4t7uaf2r69jpmno2hjq8npdu". So that domain name is the Closest Encloser of "ujs.sk". Opt-Out: True.

1. General Results, most used to calculate the result

Aname "bbbtkk.ujs.sk" is subdomain, public suffix is ".sk", top-level-domain is ".sk", top-level-domain-type is "country-code", Country is Slovakia, tld-manager is "SK-NIC, a.s.", num .sk-domains preloaded: 291 (complete: 175327)
Agood: All ip addresses are public addresses
Warning: Only one ip address found: bbbtkk.ujs.sk has only one ip address.

Agood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem

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.
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
