Header-Checks U No https result with http status 2** or 4** (standard-check) found, no header checked. 3. DNS- and NameServer - Checks 4. Content- and Performance-critical Checks http://95.3.21.33/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 95.3.21.33 Fatal: Check of /.well-known/acme-challenge/random-filename is blocked, http connection error. 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. A Info: No img element found, no alt attribute checked A Duration: 88820 milliseconds, 88.820 seconds
