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.

7. Comments


1. General Results, most used to calculate the result

Aname "promotechcomputersolutions.com" is domain, public suffix is "com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services"
Agood: All ip addresses are public addresses
Agood: No asked Authoritative Name Server had a timeout
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: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):0 complete Content-Type - header (4 urls)
http://promotechcomputersolutions.com/ 185.27.134.142

Url with incomplete Content-Type - header - missing charset
http://www.promotechcomputersolutions.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 185.27.134.142


Url with incomplete Content-Type - header - missing charset
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: No https - result with http-status 200, no encryption
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.

Content problems or problems with resources included - http links, files doesn't exist, different Content-Type definitions. Not used to calculate the result because it's a http - check. But listed so you should fix it.

Fatal: 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.: ns1.epizy.com (198.251.86.152): Delegation: ns1.epizy.com,ns2.epizy.com, Zone: ns2.epizy.com

AGood: Nameserver supports TCP connections: 2 good Nameserver
AGood: Nameserver supports Echo Capitalization: 2 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 2 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 2 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.

3. Content- and Performance-critical Checks

Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 2 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 2 complete.
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
