SSL issue on centos7

i download mod_ssl "yum install mod_ssl" After than i add some code on "/etc/httpd/conf.d/ssl.conf" The code is ;

<VirtualHost *:443>
 DocumentRoot "/var/www/aa.com"
 SSLEngine on
 SSLCertificateFile "/etc/pki/tls/certs/www_aa_com.crt"
 SSLCertificateKeyFile "/etc/pki/tls/certs/www_aa_com.key"
 SSLCertificateChainFile "/etc/pki/tls/certs/aa.ca-bundle"
</VirtualHost>

I opened firewall too.

sudo firewall-cmd --permanent --add-port=443/tcp

there is not any error message on httpd/error_log the httpd.service status is fine there is not any error too. but SSL doesn't work.

aa.com is working without ssl.

httpd.service status result ;
