	DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "b7ldajjdgmuvnqkikfatndh6v3tar1s1" between the hashed NSEC3-owner "7l3vfe90hksgohl2866i463e60k18tan" and the hashed NextOwner "di9m0at1gcrn0809c92h5c7c74kelcn7".

	DS-Query in the parent zone sends valid NSEC3 RR with the Hash "o2v72b9d7ouhnphf06reko02tl1af569" as Owner. That's the Hash of "snowsong.org" with the NextHashedOwnerName "p8vmd4uagu13udaf98m82lbrfmshnq2a". So that domain name is the Closest Encloser of "www.snowsong.org". Opt-Out: False.

	The ClosestEncloser says, that "*.snowsong.org" with the Hash "l3qciv3o1rj40qbcfs1v0g3pntlpshe4" is a possible Wildcard of the DS Query Name. But the DS-Query in the parent zone sends a valid NSEC3 RR With the owner "jd7tg8u607sb8gsgc5dps1a0vg24ts3e" and the Next Owner "o2v72b9d7ouhnphf06reko02tl1af569", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

	1. General Results, most used to calculate the result
A	name "snowsong.org" is domain, public suffix is ".org", top-level-domain is ".org", top-level-domain-type is "generic", tld-manager is "Public Interest Registry (PIR)", num .org-domains preloaded: 10357 (complete: 276475)
A	Good: All ip addresses are public addresses
	Warning: Only one ip address found: snowsong.org 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: snowsong.org has no ipv6 address.
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.
	Info: Checking the ip addresses of that domain name not exact one certificate found. So it's impossible to check if that domain requires Server Name Indication (SNI).: Domain snowsong.org, 1 ip addresses.
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.snowsong.org
	2. Header-Checks
U			No https result with http status 2 or 4 (standard-check) found, no header checked.
	3. DNS- and NameServer - Checks

	4. Content- and Performance-critical Checks
	http://snowsong.org/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 98.54.167.189	-14	Fatal: Check of /.well-known/acme-challenge/random-filename has a timeout. 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.
A	Info: No img element found, no alt attribute checked
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
