7. Comments

	1. General Results, most used to calculate the result
A	name "icinga-demo.ics.muni.cz" is subdomain, public suffix is "cz", top-level-domain-type is "country-code", Country is Czechia, tld-manager is "CZ.NIC, z.s.p.o"
A	Good: All ip addresses are public addresses
A	Good: destination is https
A	Good - only one version with Http-Status 200
A	Good: one preferred version: non-www is preferred
A	Good: every https has a Strict Transport Security Header
A	Good: HSTS max-age is long enough, 63072000 seconds = 730 days
A	Good: HSTS has includeSubdomains - directive
A	Good: HSTS has preload directive
	Warning: HSTS preload sent, but not in Preload-List. Never send a preload directive if you don't know what preload means. Check https://hstspreload.org/ to learn the basics about the Google-Preload list. If you send a preload directive, you should immediately add your domain to the HSTS preload list via https://hstspreload.org/ . If Google accepts the domain, so the status is "pending": Note that new entries are hardcoded into the Chrome source code and can take several months before they reach the stable version. So you will see this message some months. If you don't want that or if you don't understand "preload", but if you send a preload directive and if you have correct A-redirects, everybody can add your domain to that list. Then you may have problems, it's not easy to undo that. So if you don't want your domain preloaded, remove the preload directive.
	HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
A	Good: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):1 complete Content-Type - header (2 urls)
	https://icinga-demo.ics.muni.cz/ 147.251.7.9			Url with incomplete Content-Type - header - missing charset
A	http://icinga-demo.ics.muni.cz/ 147.251.7.9	302	https://icinga-demo.ics.muni.cz/	Correct redirect http - https with the same domain name

A	Good: All SOA have the same Serial Number
A	Good: CAA entries found, creating certificate is limited: digicert.com is allowed to create certificates
A	Good: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates
	4. Content- and Performance-critical Checks
A	Good: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. 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
