| 4. Content- and Performance-critical Checks |
| http://cloud.skylar.no/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 13.81.98.111
|
| Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 401 / 403 Not Allowed / Forbidden. A http status 404 - Not Found - is expected. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
|
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
