DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "o2v1ra25q7c79t0uiurjp4rdsg0ble8r" between the hashed NSEC3-owner "o2v1r66vuqd9iu3r7c8h9ol85vucln7n" and the hashed NextOwner "o2v57kqme7vl15rjdup5igccm9o9ingv". So the parent zone confirmes the not-existence of a DS RR.

7. Comments


1. General Results, most used to calculate the result

Aname "gatewaygrhum.insa-lyon.fr" is subdomain, public suffix is ".fr", top-level-domain 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.)", num .fr-domains preloaded: 3414 (complete: 240622)
AGood: All ip addresses are public addresses
Warning: Only one ip address found: gatewaygrhum.insa-lyon.fr 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: gatewaygrhum.insa-lyon.fr 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
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)
CError - no version with Http-Status 200

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 different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain gatewaygrhum.insa-lyon.fr, 1 ip addresses.
BNo _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.gatewaygrhum.insa-lyon.fr

2. Header-Checks

Agatewaygrhum.insa-lyon.fr 134.214.181.115
Content-Security-Policy
Ok: Header without syntax errors found: default-src 'self' http: https: ws: wss: data: blob: 'unsafe-inline'; frame-ancestors 'self';
F

Bad: default-src with "*" or a scheme found. That allows too much, don't use such a definition.
F

Bad: default-src with 'unsafe-inline' or 'unsave-eval'. That's dangerous, don't use it.
E

Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.
A

Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
E

Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
E

Critical: No object-src defined, the default-src used as fallback allows too much. object / embed / applet shouldn't be able to load these resources.
E

Critical: No script-src defined, the default-src used as fallback allows too much. script-src should always restricted.
F

Dangerous: No script-src defined, but the default-src as fallback allows the data: schema. That allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
F

Dangerous: No frame-src defined, but the default-src used as fallback allows the data: schema. That allows hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.

http://gatewaygrhum.insa-lyon.fr/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 134.214.181.115
-14

Fatal: Check of /.well-known/acme-challenge/random-filename has a timeout. Creating a Letsencrypt certificate via http-01 challenge can't work. You need a running webserver (http) and an open port 80. If it's a home server + ipv4, perhaps a correct port forwarding port 80 extern ⇒ working port intern is required. Port 80 / http can redirect to another domain port 80 or port 443, but not other ports. If it's a home server, perhaps your ISP blocks port 80. Then you may use the dns-01 challenge. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
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
