DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "i081btkia8h0nps97mr2si0t9t2ghv3o" between the hashed NSEC3-owner "i081btkia8h0nps97mr2si0t9t2ghv3o" and the hashed NextOwner "i081sm81t50lhq9uf19tp35rhra2u086".

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.

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.

Fatal: Check of /.well-known/acme-challenge/random-filename has different answers checking ipv6 / ipv4. Ipv6 doesn't have the expected result http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 validation may not work. Checking the validation file in /.well-known/acme-challenge Letsencrypt prefers ipv6. Two options: Remove your ipv6 / AAAA DNS entry or (better) fix your ipv6, so your webserver handles ipv6 correct. Perhaps add "Listen [::]:80". Don't use <VirtualHost ip-address:80>, switch to <VirtualHost *:80>. If you use IIS, check your bindings. Don't select a single ip address. Use this tool to check your raw ipv6 address. Add your domain name in the "Hostname" - field. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

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.
AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AInfo: No img element found, no alt attribute checked
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
