virtual host problem

[nike]

Sir,
I have one apache VPS web server on centos 7. Also i am not using plesk or cpannel . One website is running fine but when i going to host another domain from the same server it is not running perfectly. If i run second domain's website using yyyy.com or https://yyyy.com sometimes it automatically redirects to 1st one( xxxx.com ) specially it happens on https://yyyy.com . But i already redirect it in a non-ssl.conf file like this

<VirtualHost *:80>
ServerName yyyy.com
Redirect "/" "https://www.yyyy.com"
</VirtualHost>


Below is httpd -S result

VirtualHost configuration:
*:80 is a NameVirtualHost
default server www.xxxx.com (/etc/httpd/conf.d/non-ssl.conf:1)
port 80 namevhost www.xxxx.com (/etc/httpd/conf.d/non-ssl.conf:1)
port 80 namevhost yyyy.com (/etc/httpd/conf.d/non-ssl.conf:7)
*:443 is a NameVirtualHost
default server www.xxxx.com (/etc/httpd/conf.d/ssl.conf:56)
port 443 namevhost www.xxxx.com (/etc/httpd/conf.d/ssl.conf:56)
port 443 namevhost www.yyyy.com (/etc/httpd/conf.d/yyyy.conf:1)
