| Error - Certificate isn't trusted, RemoteCertificateNameMismatch
|
| Fatal: More then one ip address per domain name found, but checking all ip addresses different http status found.: Domain gitlab.rlp.net, 4 ip addresses, 2 different http results.
|
| 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 gitlab.rlp.net, 4 ip addresses, 1 different http results.
|
| B | No _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.gitlab.rlp.net
|
| 2. Header-Checks |
| A | gitlab.rlp.net
| Content-Security-Policy
| Ok: Header without syntax errors found:
|
| F |
|
| Bad: Missing default-src directive. A default-src directive is used if one of the specialized fetch directives (child-src, connect-src, font-src, frame-src, img-src, manifest-src, media-src, object-src, prefetch-src, script-src, style-src, worker-src) isn't defined. Missing default-src, all sources are allowed, that's bad. A default-src with 'none' or 'self' blocks that.
|
| 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.
|
| E |
|
| Bad: No frame-ancestors directive found. Use one to limit the pages allowed to use this page in 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.
|
| F |
|
| Critical: No object-src and no default-src as fallback defined. So object / embed / applet can load every resource. That's fatal.
|
| F |
|
| Critical: No script-src and no default-src as fallback defined. So scripts are unlimited. That's fatal.
|
| A |
| X-Content-Type-Options
| Ok: Header without syntax errors found: nosniff
|
| A |
| Referrer-Policy
| Ok: Header without syntax errors found: strict-origin-when-cross-origin
|
| A |
| Permissions-Policy
| Ok: Header without syntax errors found: interest-cohort=()
|
| A |
| X-Frame-Options
| Ok: Header without syntax errors found: SAMEORIGIN
|
| B |
|
| Info: Header is deprecated. May not longer work in modern browsers. SAMEORIGIN. Better solution: Use a Content-Security-Policy Header with a frame-ancestors directive. DENY - use 'none', SAMEORIGIN - use 'self'. If you want to allow some domains to frame your page, add these urls.
|
| A |
| X-Xss-Protection
| Ok: Header without syntax errors found: 1; mode=block
|
| B |
|
| Info: Header is deprecated. May not longer work in modern browsers. 1; mode=block
|
| 3. DNS- and NameServer - Checks |
| A | Info:: 6 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
|
| A | Info:: 6 Queries complete, 4 with IPv6, 2 with IPv4.
|
| Warning: Only some DNS Queries done via ipv6. IPv6 is the future, so the name servers of your name servers should have ipv6 addresses.
|
| A | Good: Some ip addresses of name servers found with the minimum of two DNS Queries. One to find the TLD-Zone, one to ask the TLD-Zone.ns-extern.zdv.uni-mainz.de (134.93.144.7)
|
| A | Good (1 - 3.0):: An average of 3.0 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 2 different Name Servers found: ns-extern.zdv.uni-mainz.de, xlink1.xlink.net, 2 Name Servers included in Delegation: ns-extern.zdv.uni-mainz.de, xlink1.xlink.net, 2 Name Servers included in 1 Zone definitions: ns-extern.zdv.Uni-Mainz.DE, xlink1.xlink.net, 1 Name Servers listed in SOA.Primary: ns-extern.zdv.uni-mainz.de.
|
| A | Good: Only one SOA.Primary Name Server found.: ns-extern.zdv.uni-mainz.de.
|
| A | Good: SOA.Primary Name Server included in the delegation set.: ns-extern.zdv.uni-mainz.de.
|
| A | Good: 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: ns-extern.zdv.Uni-Mainz.DE, xlink1.xlink.net
|
| A | Good: All Name Server Domain Names have a Public Suffix.
|
| A | Good: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
|
| A | Good: All Name Server ip addresses are public.
|
| A | Good: Minimal 2 different name servers (public suffix and public ip address) found: 2 different Name Servers found
|
| Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 2 different Name Servers found
|
| A | Good: Name servers with different Top Level Domains / Public Suffix List entries found: 2 Name Servers, 2 Top Level Domains: de, net
|
| A | Good: Name Servers with different domain names found.: 2 different Domains found
|
| Warning: All Name Servers from the same Country / IP location.: 2 Name Servers, 1 Countries: DE
|
| A | Info: Ipv4-Subnet-list: 2 Name Servers, 2 different subnets (first Byte): 134., 194., 2 different subnets (first two Bytes): 134.93., 194.45., 2 different subnets (first three Bytes): 134.93.144., 194.45.97.
|
| A | Excellent: Every Name Server IPv4-address starts with an unique Byte.
|
| A | Good: Nameserver supports TCP connections: 1 good Nameserver
|
| A | Good: Nameserver supports Echo Capitalization: 1 good Nameserver
|
| A | Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 1 good Nameserver
|
| A | Good: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 1 good Nameserver
|
| Nameserver doesn't pass all EDNS-Checks: ns-extern.zdv.uni-mainz.de: 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.
|
| A | Good: 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.
|
| 4. Content- and Performance-critical Checks |
| A | Good: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
|
| https://gitlab.rlp.net/users/sign_in
|
| 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.

|
| A | Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
|
| A | Info: No img element found, no alt attribute checked
|
| A | Good: 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
