DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed domain name between the hashed NSEC3-owner and the hashed NextOwner. So the parent zone confirmes the non-existence of a DS RR.

6. Comments (GZip / Html minfied / Cache-Control is beta)

Aname "srv-a.kameleon.fr" is subdomain, public suffix is "fr", top-level-domain-type is "country-code", Country is France, tld-manager is "Association Française pour le Nommage Internet en Coopération (A.F.N.I.C.)"
Agood: All ip addresses are public addresses
Agood: No asked Authoritative Name Server had a timeout
Agood: one preferred version: non-www is preferred
AGood: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):3 complete Content-Type - header (5 urls)
http://srv-a.kameleon.fr/ 163.172.131.140

correct redirect http - https with the same domain name
Bhttps://srv-a.kameleon.fr/ 163.172.131.140
200

Missing HSTS-Header
CError - 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.
HFatal error: http result with http-status 200, no encryption. Add a redirect http ⇒ https, so every connection is secure. 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.
Mhttps://www.srv-a.kameleon.fr/ 163.172.131.140

Misconfiguration - main pages should never send http status 400 - 499

Error - Certificate isn't trusted, RemoteCertificateNameMismatch, RemoteCertificateChainErrors
OOld connection: SHA1 as Hash Algorithm is deprecated. Switch to SHA256 or SHA384. If your certificate has SHA256, first check your domain via ssllabs.com and update weak Cipher Suites. Forward Secrecy support is required. The part "Cipher Suites" should have a preference. First Cipher Suite with SHA instead of SHA256 or higher - that's the problem, change that. If that doesn't help, check if there is an old Firewall / router or something else, that supports only SHA1. Update that component.
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: d.ext.nic.fr: OP100: ok. FLAGS: ok. V1: ok. V1OP100: ok. V1FLAGS: ok. DNSSEC: ok. V1DNSSEC: ok. NSID: SOA expected, but NOT found, NOERR expectend and NOERR found, Version 0 expectend and found. COOKIE: fatal timeout. CLIENTSUBNET: ok.
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.
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: 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
