SSL with Apache and Passenger - ruby-on-rails

Question

I tried to add SSL support to my server with configuration from http://www.napcsweb.com/blog/2012/07/24/securing-a-rails-app-on-passenger-with-ssl/
#<VirtualHost *:80>
# ServerName 54.215.6.127
# RewriteEngine On
# RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=permanent]
#</VirtualHost>
<VirtualHost *:80>
#<VirtualHost *:443>
ServerName 54.215.6.127
# !!! Be sure to point DocumentRoot to 'public'!
DocumentRoot /home/ubuntu/my_app/current/public
<Directory /home/ubuntu/my_app/current/public>
Satisfy Any
# This relaxes Apache security settings.
AllowOverride all
Require all granted
# MultiViews must be turned off.
Options -MultiViews
</Directory>
#SSLEngine on
#SSLOptions +StrictRequire
#SSLCertificateFile /etc/apache2/certs/54.215.6.127.crt
#SSLCertificateKeyFile /etc/apache2/certs/54.215.6.127.key
</VirtualHost>
See that I commented line to set server to previous state, i.e. non SSL, but now server is unresponsive.
I do have keys as suggested in napcsweb blog: key, csr, and crt.
What am I missing in SSL configuration?
Passenger just stopped working, how could I start it again?
Update
It worked but just with http after change configuration, I commented:
#Satisfy Any
# This relaxes Apache security settings.
#AllowOverride all
#Require all granted
# MultiViews must be turned off.
Options -MultiViews
And restarted server
sudo apachectl restart
sudo service apache2 restart
But anyway, I need to set https.
Update 2
Ports 80 and 443 are listening, but for some reason 443 does not respond.

Answer 1

I had an error in my EC2 security group. I allowed access to port 443 and it worked.
