Hint: The Certificate Authority failed to verify the temporary Apache configuration changes made by Certbot. Ensure that the listed domains point to this Apache server and that it is accessible from the internet.
My web server is (include version): Apache/2.4.52 (Ubuntu)
The operating system my web server runs on is (include version): Ubuntu 22.04.3 LTS
My hosting provider, if applicable, is: self-hosted server
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 2.6.0
But the site is available under the domain name. But for IP - no.
But, I can only see it with a "human" browser. If I try with something more programmatic, I get a timeout just like Let's Encrypt. Some kind of software is doing that, either on your part, or your ISP.
