	https://www.rk-computer.org/ 217.160.0.46	200		Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
	https://www.rk-computer.org/ 217.160.0.46	200		Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
A	Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
	https://www.rk-computer.org/ 217.160.0.46	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.: 7 script elements without defer/async.
A	Good: All CSS / JavaScript files are sent with GZip. That reduces the content of the files. 14 external CSS / JavaScript files found
A	Good: All images with internal compression not sent via GZip. Images (.png, .jpg) are already compressed, so an additional GZip isn't helpful. 3 images (type image/png, image/jpg) found without additional GZip. 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. 0 external CSS / JavaScript files without Cache-Control-Header, 2 with Cache-Control, but no max-age, 3 with Cache-Control max-age too short (minimum 7 days), 9 with Cache-Control long enough, 14 complete.
	Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 image files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 6 with Cache-Control max-age too short (minimum 7 days), 1 with Cache-Control long enough, 7 complete.
A	Good: All checked attribute values are enclosed in quotation marks (" or ').
A	Good: Some img-elements have a valid alt-attribute.: 7 img-elements found, 4 img-elements with correct alt-attributes (defined, not an empty value).
	Wrong: img-elements without alt-attribute or empty alt-attribute found. The alt-attribute ("alternative") is required and should describe the img. So Screenreader and search engines are able to use these informations.: 3 img-elements without alt-attribute, 0 img-elements with empty alt-attribute found.
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
