It is an Internet standard and normally used with TCP port 80. Almost all websites in the world support HTTP, but websites that have been configured with or some other method of setting up HTTPS may automatically redirect users from the HTTP version of the site to the HTTPS version.

From our Glossary that is already online Website That’s Already Online is usually meant to be used to switch an existing HTTP site to work in HTTPS (and, afterward, to continue renewing the site’s HTTPS certificates whenever necessary). Some documentation assumes or recommends that you have a working web site that can already be accessed using HTTP on port 80. That means, for example, that if you use a web browser to go to your domain using http://, your web server answers and some kind of content comes up (even if it’s just a default welcome page rather than the final version of your site). Some methods of using have this as a prerequisite, so you’ll have a smoother experience if you already have a site set up with HTTP.

From our Glossary with an open port 80 Port 80 Different Internet services are distinguished by using different TCP port numbers. Unencrypted HTTP normally uses TCP port 80, while encrypted HTTPS normally uses TCP port 443. To use certbot –webroot, certbot –apache, or certbot –nginx, you should have an existing HTTP website that’s already online hosted on the server where you’re going to use . This site should be available to the rest of the Internet on port 80. To use certbot –standalone, you don’t need an existing site, but you have to make sure connections to port 80 on your server are not blocked by a firewall, including a firewall that may be run by your Internet service provider or web hosting provider. Please check with your ISP or hosting provider if you’re not sure. (Using DNS validation does not require Let’s Encrypt to make any inbound connection to your server, so with this method in particular it’s not necessary to have an existing HTTP website or the ability to receive connections on port 80.)
