	https://tax-sync-c683338d.base44.app/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de	200		Warning: Not existing ACME-file, but Server sends 200, not 404 or redirect. May be a problem creating a Letsencrypt certificate. Checking /.well-known/acme-challenge/random-filename - a http status 404 - Not Found - is expected. If your server sends content and a http status 200, the validation file (87 bytes, token, dot and the hash of the public part of the account key) may be invisible, so Letsencrypt can't validate your domain. If it is an application that sends this content, perhaps create an exception, so /.well-known/acme-challenge sends raw files. Or create a redirect to another domain and / or port 443, but your Letsencrypt client must support such a solution. Certbot: Use webroot as authenticator - https://certbot.eff.org/docs/using.html 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).
A	Good: No https + http status 200 with inline CSS / JavaScript found
A	Good: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
A	Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
A	Good: Some script Elements (type text/javascript) with a src-Attribute have a defer / async - Attribute. So loading and executing these JavaScripts doesn't block parsing and rendering the Html-Output.
	https://tax-sync-c683338d.base44.app/ 216.24.57.7	200		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.: 1 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. 18 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. 15 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 6 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 21 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. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
