Wrong redirect one domain http to other domain https. First redirect to https without new dns query, so the server can send the HSTS header. That's fundamental using HSTS (Http Strict Transport Security). First step: Add correct redirects http ⇒ https. 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. Then recheck your domain, should be Grade C. There is the rule to select one https version as preferred version.

Info: Header-Element is deprecated. block-all-mixed-content
A

Good: default-src directive only with 'none' or 'self', additional sources are blocked.
A

Good: default-src without 'unsafe-inline' or 'unsave-eval'.
A

Good: form-action directive found. That reduces the risk sending data to unwanted domains. form-action is a navigation-directive, so default-src isn't used.
A

Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
A

Good: base-uri directive found. That limits the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
A

Good: No object-src found, but the default-src used as fallback is defined and restricted.
A

Good: script-src without 'unsafe-inline' and 'unsafe-eval' found. That's the recommended configuration.
A

Good: script-src without * and a scheme found.
A

Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
A

Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection.

AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: 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://f-droid.org/ 37.218.243.72
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.: 2 script elements without defer/async.

AGood: All svg-Images greater 1024 Bytes without internal compression are compressed. Svg is an Xml-Application, so Compression reduces the size of the file. 18 images (type image/svg+xml, image/x-icon, image/vnd.microsoft.icon) found with compression.
Warning: CSS / JavaScript found without Compression. Compress these ressources, gzip, deflate, br are checked. 12 external CSS / JavaScript files without Compression found - 12 with Compression, 24 complete
AGood: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 18 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. 0 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), 18 with Cache-Control long enough, 24 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, 12 with Cache-Control max-age too short (minimum 7 days), 24 with Cache-Control long enough, 36 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: Some img-elements have a valid alt-attribute.: 36 img-elements found, 30 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.: 6 img-elements without alt-attribute, 0 img-elements with empty alt-attribute found.
AGood: 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
AInfo: Different Server-Headers found
