I installed correctly certbot on my server but when i go to https://asfundation.it it load for a few minutes and then it response with "impossible to reach this website".
I need help please
I cannot reach your site using HTTP or with HTTPS. Thing to check would be any firewalls to make sure both port 80 and port 443 are open. Also check that the IP address in your DNS is still the correct one. I tried checking from multiple locations and I could not reach you on any of those.
I believe you have a firewall (and / or router) between your server and the Internet that is filtering (blocking) access to Port 443 on your server, thus HTTPS is failing to connect.

That's a good point, Certbot still assumes that people setting up HTTPS (which always defaults to TCP port 443) know at least a little bit of what it is and how it works - it's debatable whether it's Certbots job to tell you that sort of thing or not but we do see people here every day having problems because they don't know which ports to open.
