1. General Results, most used to calculate the result

Aname "maths.freeboxos.fr" is domain, public suffix is ".freeboxos.fr", top-level-domain is ".fr", top-level-domain-type is "country-code", Country is France, tld-manager is "Association Française pour le Nommage Internet en Coopération (A.F.N.I.C.)", num .fr-domains preloaded: 2038 (complete: 151507)
Agood: All ip addresses are public addresses
AGood: Minimal 2 ip addresses per domain name found: maths.freeboxos.fr has 2 different ip addresses (authoritative).

Fatal: Check of /.well-known/acme-challenge/random-filename has a timeout. 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.

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
