So the parent zone confirmes the not-existence of a DS RR.

0 DS RR in the parent zone found






DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "c4h7ie491dkkn6t4vq9srujsqerl6139" between the hashed NSEC3-owner "abbt40ssc2dqlv18ulevbenatreppv2c" and the hashed NextOwner "dikqja5dr4rt4ih2cj0o2o5947410i5q". So the parent zone confirmes the not-existence of a DS RR.
Bitmap: A, RRSIG Validated: RRSIG-Owner abbt40ssc2dqlv18ulevbenatreppv2c.co3app.com., Algorithm: 8, 3 Labels, original TTL: 86400 sec, Signature-expiration: 25.08.2022, 00:00:00 +, Signature-Inception: 04.08.2022, 00:00:00 +, KeyTag 19173, Signer-Name: co3app.com






DS-Query in the parent zone sends valid NSEC3 RR with the Hash "7vrik77o6ems99f5etm1nluosfgok11n" as Owner. That's the Hash of "efa.co3app.com" with the NextHashedOwnerName "86n3a67jsje4a36vcpq0k2ipt5apiamu". So that domain name is the Closest Encloser of "www.efa.co3app.com". Opt-Out: False.
Bitmap: A, MX, RRSIG Validated: RRSIG-Owner 7vrik77o6ems99f5etm1nluosfgok11n.co3app.com., Algorithm: 8, 3 Labels, original TTL: 86400 sec, Signature-expiration: 25.08.2022, 00:00:00 +, Signature-Inception: 04.08.2022, 00:00:00 +, KeyTag 19173, Signer-Name: co3app.com






The ClosestEncloser says, that "*.efa.co3app.com" with the Hash "i93kg6r060v19gr2okp9ucthou498d4d" is a possible Wildcard of the DS Query Name. But the DS-Query in the parent zone sends a valid NSEC3 RR With the owner "hg8hcpssssmambmrilqdcqu13j1ebs7u" and the Next Owner "npu12psg3oucjcfv5c4dc5ns144asc56", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.
Bitmap: No Bitmap? Validated: RRSIG-Owner hg8hcpssssmambmrilqdcqu13j1ebs7u.co3app.com., Algorithm: 8, 3 Labels, original TTL: 86400 sec, Signature-expiration: 25.08.2022, 00:00:00 +, Signature-Inception: 04.08.2022, 00:00:00 +, KeyTag 19173, Signer-Name: co3app.com

7. Comments


1. General Results, most used to calculate the result

Aname "efa.co3app.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: 63591 (complete: 175327)
AGood: All ip addresses are public addresses
Warning: Only one ip address found: efa.co3app.com has only one ip address.
Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: efa.co3app.com has no ipv6 address.
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: No cookie sent via http.
AGood: every https has a Strict Transport Security Header
AGood: HSTS max-age is long enough, 31536000 seconds = 365 days
AGood: HSTS has includeSubdomains - directive
AGood: HSTS has preload directive
Warning: HSTS preload sent, but not in Preload-List. Never send a preload directive if you don't know what preload means. Check https://hstspreload.org/ to learn the basics about the Google-Preload list. If you send a preload directive, you should **immediately** add your domain to the HSTS preload list via https://hstspreload.org/ . If Google accepts the domain, so the status is "pending": Note that new entries are hardcoded into the Chrome source code and can take several months before they reach the stable version. So you will see this message some months. If you don't want that or if you don't understand "preload", but if you send a preload directive and if you have correct A-redirects, everybody can add your domain to that list. Then you may have problems, it's not easy to undo that. So if you don't want your domain preloaded, remove the preload directive.
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)

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 efa.co3app.com, 1 ip addresses, 1 different http results.

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.dotroll.com: 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
AGood: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates
AGood: CAA entries found, creating certificate is limited: sectigo.com is allowed to create certificates

4. Content- and Performance-critical Checks

AGood: 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.
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 %.

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 images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 1 image files with long Cache-Control max-age found
AGood: 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.: 1 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
