| http://portal.reffnet.ch/de/Account/Login?ReturnUrl=%2F
| Wrong redirect one domain http to other domain http. First redirect to https without changing the domain, so no new dns query is required. So the server can send the HSTS header. That's fundamental using HSTS (Http Strict Transport Security). First step: Add correct redirects http ⇒ https. 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. Then recheck your domain, should be Grade C. There is the rule to select one https version as preferred version.

| 2. Header-Checks |
| A | portal.reffnet.ch
| Content-Security-Policy
| Ok: Header without syntax errors found: frame-ancestors https://www.reffnet.ch https://www.reffnet.ch/de/erfportal https://www.reffnet.ch/it/erfportal https://www.reffnet.ch/fr/erfportal https://reffnet.ch https://reffnet.ch/de/erfportal https://reffnet.ch/it/erfportal https://reffnet.ch/fr/erfportal
|
| F |
|
| Bad: Missing default-src directive. A default-src directive is used if one of the specialized fetch directives (child-src, connect-src, font-src, frame-src, img-src, manifest-src, media-src, object-src, prefetch-src, script-src, style-src, worker-src) isn't defined. Missing default-src, all sources are allowed, that's bad. A default-src with 'none' or 'self' blocks that.
|
| E |
|
| Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.
|
| A |
|
| Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
|
| E |
|
| Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
|
| F |
|
| Critical: No object-src and no default-src as fallback defined. So object / embed / applet can load every resource. That's fatal.
|
| F |
|
| Critical: No script-src and no default-src as fallback defined. So scripts are unlimited. That's fatal.
|
| F | portal.reffnet.ch
| X-Content-Type-Options
| Critical: Missing Header:

| 3. DNS- and NameServer - Checks |
| A | Info:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 3 Name Servers.
|
| A | Info:: 2 Queries complete, 2 with IPv6, 0 with IPv4.
|
| A | Good: All DNS Queries done via IPv6.
|
| A | Good: Some ip addresses of name servers found with the minimum of two DNS Queries. One to find the TLD-Zone, one to ask the TLD-Zone.ns1.netzone.ch (212.243.197.4), ns2.netzone.ch (194.209.26.3), ns3.netzone.ch (212.243.2.253)
|
| A | Good (1 - 3.0):: An average of 0.7 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 3 different Name Servers found: ns1.netzone.ch, ns2.netzone.ch, ns3.netzone.ch, 2 Name Servers included in Delegation: ns1.netzone.ch, ns2.netzone.ch, 3 Name Servers included in 1 Zone definitions: ns1.netzone.ch, ns2.netzone.ch, ns3.netzone.ch, 1 Name Servers listed in SOA.Primary: ns1.netzone.ch.
|
| A | Good: Only one SOA.Primary Name Server found.: ns1.netzone.ch.
|
| A | Good: SOA.Primary Name Server included in the delegation set.: ns1.netzone.ch.
|
| X | 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. Read https://www.iana.org/help/nameserver-requirements and send it to your Name Server Hoster.: ns1.netzone.ch (212.243.197.4): Delegation: ns1.netzone.ch, ns2.netzone.ch, Zone: ns1.netzone.ch, ns2.netzone.ch, ns3.netzone.ch. Name Servers defined in Zone, missing in Delegation: ns3.netzone.ch.

|
| Nameserver doesn't pass all EDNS-Checks: ns1.netzone.ch: 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.
|
| A | Good: All SOA have the same Serial Number
|
| A | Good: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates
|
| 4. Content- and Performance-critical Checks |
| A | Good: 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.
|
| A | Good: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
|
| https://portal.reffnet.ch/de/Account/Login?ReturnUrl=%2F
|
| 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://portal.reffnet.ch/de/Account/Login?ReturnUrl=%2F
|
| 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://portal.reffnet.ch/de/Account/Login?ReturnUrl=%2F
|
| 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.
|
| https://portal.reffnet.ch/de/Account/Login?ReturnUrl=%2F
|
| 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.: 5 script elements without defer/async.
|
| A | Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 8 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. 0 external CSS / JavaScript files without Cache-Control-Header, 6 with Cache-Control, but no max-age, 1 with Cache-Control max-age too short (minimum 7 days), 1 with Cache-Control long enough, 8 complete.
|
| Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 1 image 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, 1 complete.
|
| A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
| A | Good: All img-elements have a valid alt-attribute.: 1 img-elements found.
|
| 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. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
