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 "cssmvdfoo004dfntv6iop4gms65gfqnn" between the hashed NSEC3-owner "cssm1knsqe7itkro3vs28ijucvaqogna" and the hashed NextOwner "cst1dg96liso3gcagup6nur4jvm3d5ck". 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 "0d790076pp5pfktg2hrthj5bj6ckckcb" as Owner. That's the Hash of "io" with the NextHashedOwnerName "0d7bd4g2j0sls1qj0ovhk6nsri6v9mik". So that domain name is the Closest Encloser of "book.io". Opt-Out: True.

Old connection: Cipher Suites without Forward Secrecy (FS) found.

Or use Tls.1.3, then all Cipher Suites use FS. 4 Cipher Suites without Forward Secrecy found
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 www.nonprod.book.io, 1 ip addresses, 1 different http results.

AInfo:: 4 different Name Servers found: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com, 4 Name Servers included in Delegation: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com, 4 Name Servers included in 1 Zone definitions: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com, 1 Name Servers listed in SOA.Primary: ns-cloud-e1.googledomains.com.
AGood: Only one SOA.Primary Name Server found.: ns-cloud-e1.googledomains.com.
AGood: SOA.Primary Name Server included in the delegation set.: ns-cloud-e1.googledomains.com.
AGood: 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-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com

AGood: All name servers have ipv4- and ipv6-addresses.: 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: googledomains.com
Warning: All Name Servers from the same Country / IP location.: 4 Name Servers, 1 Countries: US
AInfo: Ipv4-Subnet-list: 4 Name Servers, 1 different subnets (first Byte): 216., 1 different subnets (first two Bytes): 216.239., 4 different subnets (first three Bytes): 216.239.32., 216.239.34., 216.239.36., 216.239.38.

AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 8 good Nameserver
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.

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.
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
