H	Fatal error: http result with http-status 200, no encryption. Add a redirect http ⇒ https, so every connection is secure. Perhaps in your port 80 vHost something like "RewriteEngine on" + "RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]" (two rows, without the "). Don't add this in your port 443 vHost, that would create a loop.

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
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: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).

A	Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
A	Good: Some script Elements (type text/javascript) with a src-Attribute have a defer / async - Attribute. So loading and executing these JavaScripts doesn't block parsing and rendering the Html-Output.
	https://www.duckdns.org/ 3.98.169.180	200		Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 3 script elements without defer/async.

	Warning: CSS / JavaScript found without Compression. Compress these ressources, gzip, deflate, br are checked. 6 external CSS / JavaScript files without Compression found - 6 with Compression, 12 complete
A	Good: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 9 images (type image/png, image/jpg, image/jpeg, image/webp, image/gif) found without additional Compression. Not required because these images are already compressed
	Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 6 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 6 with Cache-Control max-age too short (minimum 7 days), 3 with Cache-Control long enough, 15 complete.
	Warning: Images with a missing or too short Cache-Control header found.

A	Good: All checked attribute values are enclosed in quotation marks (" or ').
	Wrong: img-elements without alt-attribute or empty alt-attribute found. The alt-attribute ("alternative") is required and should describe the img.
