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 "185.104.28.238" is ipv4 address, public suffix is not defined
Agood: All ip addresses are public addresses
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
Bhttps://185.104.28.238/ 185.104.28.238
200

Missing HSTS-Header
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.
Ihttps://185.104.28.238/ 185.104.28.238
200

Content problems or problems with resources included - http links, files doesn't exist, different Content-Type definitions. Check the Html-Content - Part.
Nhttps://185.104.28.238/ 185.104.28.238
200

Error - Certificate isn't trusted, RemoteCertificateNameMismatch, RemoteCertificateChainErrors

2. DNS- and NameServer - Checks


3. 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.
https://185.104.28.238/ 185.104.28.238
200

Warning: https result with status 200 and size greater then 1024 Bytes without GZip found. Add GZip support so the html content is compressed.
AGood: No https + http status 200 with inline CSS / JavaScript found
https://185.104.28.238/ 185.104.28.238
200

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.
https://185.104.28.238/ 185.104.28.238
200

Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.
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
