1. General Results, most used to calculate the result A name "radio.apaservsm.ro" is subdomain, public suffix is ".ro", top-level-domain is ".ro", top-level-domain-type is "country-code", Country is Romania, tld-manager is "National Institute for R&D in Informatics", num .ro-domains preloaded: 639 (complete: 221801) A Good: All ip addresses are public addresses Warning: Only one ip address found: radio.apaservsm.ro has only one ip address. Warning: Only one ip address found: www.radio.apaservsm.ro has only one ip address. Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: radio.apaservsm.ro has no ipv6 address. Warning: No ipv6 address found.

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.

DNS- and NameServer - Checks A Info:: 14 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers. A Info:: 14 Queries complete, 14 with IPv6, 0 with IPv4. A Good: All DNS Queries done via IPv6. Ok (4 - 8):: An average of 7.0 queries per domain name server required to find all ip addresses of all name servers. A Info:: 2 different Name Servers found: ns1.nameserverservice.de, ns2.nameserverservice.de, 2 Name Servers included in Delegation: ns1.nameserverservice.de, ns2.nameserverservice.de, 2 Name Servers included in 1 Zone definitions: ns1.nameserverservice.de, ns2.nameserverservice.de, 1 Name Servers listed in SOA.Primary: ns1.nameserverservice.de. A Good: Only one SOA.Primary Name Server found.: ns1.nameserverservice.de. A Good: SOA.Primary Name Server included in the delegation set.: ns1.nameserverservice.de. A Good: 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: ns1.nameserverservice.de, ns2.nameserverservice.de A Good: All Name Server Domain Names have a Public Suffix. A Good: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address. A Good: All Name Server ip addresses are public. A Good: Minimal 2 different name servers (public suffix and public ip address) found: 2 different Name Servers found Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 2 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.: 2 Name Servers, 1 Top Level Domain: de 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.

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 http://radio.apaservsm.ro/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 81.196.170.147 Fatal: Check of /.well-known/acme-challenge/random-filename is blocked, http connection error. 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. A Good: Every https result with status 200 supports GZip. https://www.radio.apaservsm.ro/login_up.php Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header. https://62.75.254.65/login_up.php Warning: Https + http status 200 + Inline CSS / JavaScript found.

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://62.75.254.65/login_up.php 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. A Good: Every https connection via port 443 supports the http/2 protocol via ALPN. https://www.radio.apaservsm.ro/login_up.php Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 7 script elements without defer/async. https://62.75.254.65/login_up.php Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute.

That reduces the content of the files. 10 external CSS / JavaScript files found Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 20 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, 20 complete. A Good: All checked attribute values are enclosed in quotation marks (" or '). A Info: No img element found, no alt attribute checked A Good: 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.
