I run the command sudo certbot certonly -d example.com -d www.example.com - sub.example.com and get the following error:
Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems: Domain: sub.example.com Type: unauthorized Detail: 12.34.56.78: Invalid response from https://www.example.com: "\r\n<!DOCTYPE html>\r\n\r\n\r\n<html xmlns=\"http://www.w3.org/1999/xhtml\" lang=\"en\">\r\n<head>\r\n"SSL was configured for the root domain and 'www' previously but I am trying to add the additional subdomain. All of the domains can be reached through a browser but sub.domain.com is the only one that says not secure.
/atc/apache2/sites-availabel/default-ssl.conf looks like this:
<IfModule mod_ssl.c><VirtualHost *:443> ServerName example.com ServerAdmin webmaster@localhost DocumentRoot /var/www/html ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined Include /etc/letsencrypt/options-ssl-apache.conf ServerAlias www.example.com, sub.example.com SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem</VirtualHost></IfModule>Am I missing something here or should I be doing something else?
