Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. [https://crt.sh/?q=example.com](https://crt.sh/?q=example.com)), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help. My domain is: [emarge.formasup-med.com](http://emarge.formasup-med.com) I ran this command: certbot --apache It produced this output: Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems: Domain: [emarge.cfa-epure.com](http://emarge.cfa-epure.com) Type: connection Detail: 51.91.111.14: Fetching [http://emarge.cfa-epure.com/.well-known/acme-challenge/\_jqRgsdxDCCCn0TlQLdShQLTjTHXci-hvdatiffLWas:](http://emarge.cfa-epure.com/.well-known/acme-challenge/_jqRgsdxDCCCn0TlQLdShQLTjTHXci-hvdatiffLWas:) Timeout during connect (likely firewall problem) My web server is (include version): Server version: Apache/2.4.52 (Ubuntu) Server built: 2023-10-26T13:44:44 The operating system my web server runs on is (include version): Ubuntu 22.04.3 LTS My hosting provider, if applicable, is: AWS I can login to a root shell on my machine (yes or no, or I don't know): yes I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no The version of my client is (e.g. output of `certbot --version` or `certbot-auto --version` if you're using Certbot): certbot 2.9.0 certbot seems to loog for an answer on 51.91.111.14 but the domain IP is 15.236.71.204 ---
