DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "35cl2uqgjq92shh9igm4pscum9j3vhrf" between the hashed NSEC3-owner "35ckus98e16rldfcd3n2qt1r65blpji0" and the hashed NextOwner "35cl5t2js29ors0l14mmic70atte9tap". 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 "ck0pojmg874ljref7efn8430qvit8bsm" as Owner. That's the Hash of "com" with the NextHashedOwnerName "ck0q1gin43n1arrc9osm6qpqr81h5m9a". So that domain name is the Closest Encloser of "0kcg.com". Opt-Out: True.

1. General Results, most used to calculate the result

Aname "srv.0kcg.com" is subdomain, public suffix is ".com", top-level-domain is ".com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .com-domains preloaded: 61113 (complete: 168171)
Agood: All ip addresses are public addresses
Warning: Only one ip address found: srv.0kcg.com has only one ip address.

AGood: Name Server IPv6 addresses from different subnets found.
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
Nameserver doesn't pass all EDNS-Checks: ns1.he.net: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
AGood: All SOA have the same Serial Number
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.

3. Content- and Performance-critical Checks

http://srv.0kcg.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 45.157.177.227
502

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 500 - 599, Server Error. Creating a Letsencrypt certificate via http-01 challenge can't work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: Every https result with status 200 supports GZip.
https://srv.0kcg.com/webmail/
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://srv.0kcg.com/webmail/
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.
https://srv.0kcg.com/webmail/
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.
https://srv.0kcg.com/webmail/
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.
AGood: All CSS / JavaScript files are sent with GZip. That reduces the content of the files. 10 external CSS / JavaScript files found
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 10 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 10 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 1 image files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 1 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: All img-elements have a valid alt-attribute.: 1 img-elements 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
