Check DNS, Urls + Redirects, Certificates and Content of your Website


Info: Problems with 3.048.289 Letsencrypt certificates (378.325 accounts). They must be revoked (revocation starts 2020-03-04 20:00 UTC) - see Revoking certain certificates on March 4. Update 2020-03-07: Good news: Mass-revocation is canceled.

This tool: A check (SerialNumber) is added. Letsencrypt has published a list of critical SerialNumbers, this list is checked. See the part "9. Certificates". If there is a warning, renew that certificate and replace the current certificate.

If root or the top level zone isn't validated, it's buggy.

DS-Query in the parent zone has a valid NSEC RR as result with the domain name between the NSEC-Owner "cu" and the NextOwner "cuisinella". So the parent zone confirmes the non-existence of a DS RR. Bitmap: NS, RRSIG, NSEC

1. General Results, most used to calculate the result

Aname "gobscu.cu" is domain, public suffix is "cu", top-level-domain-type is "country-code", Country is Cuba, tld-manager is "CENIAInternet Industria y San Jose Capitolio Nacional"
Agood: All ip addresses are public addresses
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.

2. DNS- and NameServer - Checks

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.gobscu.cu
AGood: Nameserver supports TCP connections: 1 good Nameserver
AGood: Nameserver supports Echo Capitalization: 1 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 1 good Nameserver
AGood: 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: gobscu.cu: 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.
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.

3. Content- and Performance-critical Checks

http://gobscu.cu/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 200.55.150.170
-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

8. Connections

No connection informations found. Perhaps only http - connections.


9. Certificates

No certificate informations found. Perhaps only http - connections.


10. Last Certificates - Certificate Transparency Log Check

1. Source CertSpotter - active certificates (one check per day)

No CertSpotter - CT-Log entries found


2. Source crt.sh - old and new certificates, sometimes very slow - only certificates with "not after" > 2019 are listed

No CRT - CT-Log entries found


11. Html-Content - Entries

No Html-Content entries found. Only checked if https + status 200/401/403/404


12. Nameserver - IP-Adresses (alpha)

Required Root-climbing DNS-Queries to find ip addresses of all Name Servers:

No NameServer - IP address informations found. The feature is new (2020-05-07), so recheck this domain.
