1. General Results, most used to calculate the result

Aname "eulo.ewha.ac.kr" is subdomain, public suffix is ".ac.kr", top-level-domain is ".kr", top-level-domain-type is "country-code", Country is Korea (the Republic of), tld-manager is "Korea Internet & Security Agency (KISA)"
Agood: All ip addresses are public addresses
Warning: Only one ip address found: eulo.ewha.ac.kr 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: eulo.ewha.ac.kr has no ipv6 address.
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
XFatal error: Nameserver doesn't support TCP connection: g.dns.kr / 202.31.190.1: Fatal error (-14). Details: Unable to read data from the transport connection: Eine vorhandene Verbindung wurde vom Remotehost geschlossen. - Eine vorhandene Verbindung wurde vom Remotehost geschlossen
Info: Checking the ip addresses of that domain name not exact one certificate found. So it's impossible to check if that domain requires Server Name Indication (SNI).: Domain eulo.ewha.ac.kr, 1 ip addresses.

3. Content- and Performance-critical Checks

http://eulo.ewha.ac.kr/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 203.255.170.173
-14

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.
AInfo: No img element found, no alt attribute checked
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
