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 "ncdvmqcp6gq4bs4s9k37nn3b0vckbph8" between the hashed NSEC3-owner "ncdt9jn7bcaaj4o2mqggfc847usr1obh" and the hashed NextOwner "nce2078rhilqiqr1a8gjdar3mne37c34". 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 "a1rt98bs5qgc9nfi51s9hci47uljg6jh" as Owner. That's the Hash of "net" with the NextHashedOwnerName "a1rtlnpgulogn7b9a62shje1u3ttp8dr". So that domain name is the Closest Encloser of "linkpc.net". Opt-Out: True.

Missing HSTS-Header
CError - no preferred version www or non-www. Select one version as preferred version, then add a redirect https + not-preferred version to https + preferred version. Perhaps in your port 443 vHost something like "RewriteEngine on" + "RewriteCond %{SERVER_NAME} = example.com" + "ReWriteRule ^ https://www.example.com%{REQUEST_URI} [END,QSA,R=permanent]" (three rows, without the "). That should create a redirect https + example.com ⇒ https + www.example.com. Or switch both values to use the non-www version as your preferred version.
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.

3. DNS- and NameServer - Checks

AInfo:: 11 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
AInfo:: 11 Queries complete, 5 with IPv6, 6 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.
AGood: 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.ns1.dnsexit.com (89.39.149.107), ns1.dnsexit.com (89.39.149.107)
AGood (1 - 3.0):: An average of 2.8 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 4 different Name Servers found: ns1.dnsexit.com, ns10.dnsexit.com, ns11.dnsexit.com, ns12.dnsexit.com, 3 Name Servers included in Delegation: ns10.dnsexit.com, ns11.dnsexit.com, ns12.dnsexit.com, 4 Name Servers included in 3 Zone definitions: ns1.dnsexit.com, ns2.dnsexit.com, ns3.dnsexit.com, ns4.dnsexit.com, ns10.dnsexit.com, ns11.dnsexit.com, ns12.dnsexit.com, 1 Name Servers listed in SOA.Primary: ns1.dnsexit.com.
AGood: Only one SOA.Primary Name Server found.: ns1.dnsexit.com.
Error: SOA.Primary Name Server not included in the delegation set.: ns1.dnsexit.com.
XFatal: Inconsistency 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. Read https://www.iana.org/help/nameserver-requirements and send it to your Name Server Hoster.: ns1.dnsexit.com (89.39.149.107): Delegation: ns10.dnsexit.com, ns11.dnsexit.com, ns12.dnsexit.com, Zone: ns1.dnsexit.com, ns2.dnsexit.com, ns3.dnsexit.com, ns4.dnsexit.com. Name Servers defined in Delegation, missing in Zone: ns10.dnsexit.com, ns11.dnsexit.com, ns12.dnsexit.com.Name Servers defined in Zone, missing in Delegation: ns1.dnsexit.com, ns2.dnsexit.com, ns3.dnsexit.com, ns4.dnsexit.com.
AGood: All Name Server Domain Names have a Public Suffix.
AGood: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
AGood: All Name Server ip addresses are public.
AGood: Minimal 2 different name servers (public suffix and public ip address) found: 4 different Name Servers found
Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 4 different Name Servers found
Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 4 Name Servers, 1 Top Level Domain: com
Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: dnsexit.com
AGood: Name servers with different Country locations found: 4 Name Servers, 2 Countries: RO, US
AInfo: Ipv4-Subnet-list: 4 Name Servers, 4 different subnets (first Byte): 162., 63., 69., 89., 4 different subnets (first two Bytes): 162.244., 63.141., 69.30., 89.39., 4 different subnets (first three Bytes): 162.244.82., 63.141.249., 69.30.249., 89.39.149.
AExcellent: Every Name Server IPv4-address starts with an unique Byte.
AGood: Nameserver supports Echo Capitalization: 4 good Nameserver
XNameserver Timeout checking Echo Capitalization: ns13.dnsexit.com / 104.223.143.26

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.

Two options: Remove your ipv6 / AAAA DNS entry or (better) fix your ipv6, so your webserver handles ipv6 correct. Perhaps add "Listen [::]:80". Don't use <VirtualHost ip-address:80>, switch to <VirtualHost *:80>. If you use IIS, check your bindings. Don't select a single ip address. Use this tool to check your raw ipv6 address.

AGood: All checked attribute values are enclosed in quotation marks (" or ').
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
