C	Error - no preferred version www or non-www. Select one version as preferred version, then add a redirect https + not-preferred version to https + preferred version. Perhaps in your port 443 vHost something like "RewriteEngine on" + "RewriteCond %{SERVER_NAME} = example.com" + "ReWriteRule ^ https://www.example.com%{REQUEST_URI} [END,QSA,R=permanent]" (three rows, without the "). That should create a redirect https + example.com ⇒ https + www.example.com. Or switch both values to use the non-www version as your preferred version.
C	Error - more then one version with Http-Status 200. After all redirects, all users (and search engines) should see the same https url: Non-www or www, but not both with http status 200.

A	Good: Only one SOA.Primary Name Server found.: pdns99.ultradns.com.
A	Good: SOA.Primary Name Server included in the delegation set.: pdns99.ultradns.com.
A	Good: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: pdns99.ultradns.biz, pdns99.ultradns.com, pdns99.ultradns.net, pdns99.ultradns.org

A	Good: Name Server IPv4-addresses from different subnet found:
A	Info: IPv6-Subnet-list: 4 Name Servers with IPv6, 2 different subnets (first block): 2001:, 2610:, 2 different subnets (first two blocks): 2001:0502:, 2610:00a1:, 4 different subnets (first three blocks): 2001:0502:4612:, 2001:0502:f3ff:, 2610:00a1:1014:, 2610:00a1:1015:, 4 different subnets (first four blocks): 2001:0502:4612:0000:, 2001:0502:f3ff:0000:, 2610:00a1:1014:0000:, 2610:00a1:1015:0000:

	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.

Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.

	https://staging.zuckerman.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de	404		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.

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. 2 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, 0 with Cache-Control, but no max-age, 4 with Cache-Control max-age too short (minimum 7 days), 10 with Cache-Control long enough, 14 complete.
A	Good: All images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 8 image files with long Cache-Control max-age 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. So Screenreader and search engines are able to use these informations.: 8 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
