To be more specific about Rudy's concern here, Ubuntu 11.10 is not a long-term support release and it stopped being supported by the operating system vendor (Canonical) on 2013-05-09, and also stopped receiving security updates at that time. Since that is nearly 9 years ago, there are a lot of security vulnerabilities that researchers have identified since then that would not have been patched in that system.
Perhaps this was a typo, though—I somewhat doubt that the official Certbot Ubuntu package for 0.40.0 would even install under Ubuntu 11.10 due to dependency issues.
I made a mistake on my ubuntu version it’s actually 20.4.
After adding the www to my domain it did nothing. The challenge still failed. It also made it so you can’t access it without entering www in front of the domain.
I went out o let’s debug and it said I needed to ad so me records to my domain. A added toe records. One that’s has no hostname and is a good toe a record and the other is a type a record with www hostname. I ram the command again and it had no isssues. However it still says not secure on my site. Trying to go to www.SuperiorCraft.net doesn’t work. It only works without typing the www.
Ok https is working now that I opened the port. However it’s not redirecting users to https. It’s only secure if you enter https://SuperiorCraft.net. Using the domain alone doesn’t work. How do I redirect users to https?

For SEO purposes you might want to pick either the apex (SuperiorCraft.net) or www subdomain (www.SuperiorCraft.net) then redirect all traffic to your choice.
