DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "srd96f63tkd65pcjtq9oc7m1qc38iua1" between the hashed NSEC3-owner "srd7vo98u799jlnfmo9rokk0v5598vco" and the hashed NextOwner "srdcitpaeaag5ds591frds1e3a3ktq98". So the parent zone confirmes the not-existence of a DS RR.

DS-Query in the parent zone sends valid NSEC3 RR with the Hash "tjlb7qbojvmlf1s6gdriru7vsms1lg16" as Owner. That's the Hash of "de" with the NextHashedOwnerName "tjlfjprvcmsth243pmi98vqtj9pgi7us". So that domain name is the Closest Encloser of "niemann-web.de". Opt-Out: True.

Error - Certificate isn't trusted, RemoteCertificateNameMismatch
Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain nexus.niemann-web.de, 1 ip addresses, 1 different http results.

2. Header-Checks (alpha, started 2022-10-23, may be buggy / incomplete)


3. DNS- and NameServer - Checks

AInfo:: 52 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
AInfo:: 52 Queries complete, 52 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Bad (greater 8):: An average of 13.0 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 4 different Name Servers found: ns1057.ui-dns.biz, ns1059.ui-dns.com, ns1064.ui-dns.de, ns1095.ui-dns.org, 4 Name Servers included in Delegation: ns1057.ui-dns.biz, ns1059.ui-dns.com, ns1064.ui-dns.de, ns1095.ui-dns.org, 4 Name Servers included in 1 Zone definitions: ns1057.ui-dns.biz, ns1059.ui-dns.com, ns1064.ui-dns.de, ns1095.ui-dns.org, 1 Name Servers listed in SOA.Primary: ns1095.ui-dns.org.
AGood: Only one SOA.Primary Name Server found.: ns1095.ui-dns.org.
AGood: SOA.Primary Name Server included in the delegation set.: ns1095.ui-dns.org.
AGood: 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: ns1057.ui-dns.biz, ns1059.ui-dns.com, ns1064.ui-dns.de, ns1095.ui-dns.org
AGood: All Name Server Domain Names have a Public Suffix.
AGood: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
AGood: All Name Server ip addresses are public.
AGood: Minimal 2 different name servers (public suffix and public ip address) found: 4 different Name Servers found
AGood: All name servers have ipv4- and ipv6-addresses.: 4 different Name Servers found
AGood: Name servers with different Top Level Domains / Public Suffix List entries found: 4 Name Servers, 4 Top Level Domains: de, org, com, biz
AGood: Name Servers with different domain names found.: 4 different Domains found
Warning: All Name Servers from the same Country / IP location.: 4 Name Servers, 1 Countries: DE
AInfo: Ipv4-Subnet-list: 4 Name Servers, 1 different subnets (first Byte): 217., 1 different subnets (first two Bytes): 217.160., 4 different subnets (first three Bytes): 217.160.80., 217.160.81., 217.160.82., 217.160.83.

Fatal: All Name Server IPv6 addresses from the same subnet.
AGood: Nameserver supports TCP connections: 2 good Nameserver
AGood: Nameserver supports Echo Capitalization: 2 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 2 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 2 good Nameserver

AGood: All SOA have the same Serial Number
AGood: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates

4. Content- and Performance-critical Checks

Fatal: All checks of /.well-known/acme-challenge/random-filename have a redirect, destination doesn't have the random filename. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: Every https result with status 200 supports GZip.
AGood: No https + http status 200 with inline CSS / JavaScript found
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
https://nexus.niemann-web.de/index.php/login
200

Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. 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.
AGood: All script Elements (type text/javascript) and src-Attribute have a defer / async - Attribute. So loading and executing these JavaScripts doesn't block parsing and rendering the Html-Output.
Warning: CSS / JavaScript found without GZip support. Send these ressources with GZip. 15 external CSS / JavaScript files without GZip found - 1 with GZip, 16 complete
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, 1 with Cache-Control, but no max-age, 1 with Cache-Control max-age too short (minimum 7 days), 14 with Cache-Control long enough, 16 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
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
