Hi I have installed an SSL cert from Comodo using both guides from their side and DO's side. However, i am unable to access the HTTPS variant of my site.

<IfModule mod_ssl.c>
        <VirtualHost _default_:443>
                ServerAdmin admin@atk.me
                ServerName atk.me:443
                ServerAlias www.atk.me:443

                DocumentRoot /var/www/html

                # Available loglevels: trace8, ..., trace1, debug, info, notice$
                # error, crit, alert, emerg.
                # It is also possible to configure the loglevel for particular
                # modules, e.g.
                #LogLevel info ssl:warn

                ErrorLog ${APACHE_LOG_DIR}/error.log
                CustomLog ${APACHE_LOG_DIR}/access.log combined

                # For most configuration files from conf-available/, which are
                # enabled or disabled at a global level, it is possible to
                # include a line for only one particular virtual host. For exam$
                # following line enables the CGI configuration for this host on$
                # after it has been globally disabled with "a2disconf".
                #Include conf-available/serve-cgi-bin.conf

                #   SSL Engine Switch:
                #   Enable/Disable SSL for this virtual host.
                SSLEngine on
                SSLCertificateKeyFile /etc/apache2/ssl/atk-me.key
                SSLCertificateFile /etc/apache2/ssl/atk-me.crt
                SSLCertificateChainFile /etc/apache2/ssl/atk-me.ca-bundle

Above is my ssl configuration.

Any help will be greatly appreciated.

If it helps, my certificate is under Comodo and is reissued.
