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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Since you mentioned you did execute all commands from the above tutorial, could you show output of the command sudo certbot certificates?
Looking at your server and logs, you did have certificate for your root domain. However, your apache webserver only listens on port 80 not port 443. You might want to check your Apache configuration and see what's wrong.
