	1. General Results, most used to calculate the result
A	name "portal.ines.co.rs" is subdomain, public suffix is ".co.rs", top-level-domain is ".rs", top-level-domain-type is "country-code", Country is Serbia, tld-manager is "Serbian National Internet Domain Registry (RNIDS)", num .rs-domains preloaded: 64 (complete: 142558)
A	good: All ip addresses are public addresses
	Warning: Only one ip address found: portal.ines.co.rs 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: portal.ines.co.rs 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.
N	89.216.28.158:8080		Error - Certificate isn't trusted, RemoteCertificateNameMismatch
	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 portal.ines.co.rs, 1 ip addresses.
	2. DNS- and NameServer - Checks
A	Info:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
A	Info:: 2 Queries complete, 1 with IPv6, 1 with IPv4.
	Warning: Only some DNS Queries done via ipv6. IPv6 is the future, so the name servers of your name servers should have ipv6 addresses.
A	Good: Some ip addresses of name servers found with the minimum of two DNS Queries. One to find the TLD-Zone, one to ask the TLD-Zone.ns1.loopia.se (93.188.0.20), ns2.loopia.se (2a02:250:ffff::21, 93.188.0.21)
A	Good (1 - 3.0):: An average of 1.0 queries per domain name server required to find all ip addresses of all name servers.
A	Info:: 2 different Name Servers found: ns1.loopia.se, ns2.loopia.se, 2 Name Servers included in Delegation: ns1.loopia.se, ns2.loopia.se, 2 Name Servers included in 1 Zone definitions: ns1.loopia.se, ns2.loopia.se, 1 Name Servers listed in SOA.Primary: ns1.loopia.se.

	http://portal.ines.co.rs/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 89.216.28.158	-3	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.
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
