I have hosted two wordpress websites on single droplet and trying to host another one which is xyz.com but the problem is that when I open xyz.com it redirects to my default server domain name abc.com please help me in this, I am stuck from 2 days.
DNS setting:
A record @ 198.xxx.xxx.xxx
CNAME:www xyz.com.
CNAME:* xyz.com.
ns:ns1.digitalocean.com.
ns:ns2.digitalocean.com.
ns:ns2.digitalocean.com.

Server Block:

server {
listen 80;
listen [::]:80;

root /var/www/xyz.com/html;
index index.php index.html index.htm;

# Make site accessible from http://localhost/
server_name xyz.com www.xyz.com;

location / {
    # First attempt to serve request as file, then
    # as directory, then fall back to displaying a 404.
    try_files $uri $uri/ /index.php?$args;
    # Uncomment to enable naxsi on this location
    # include /etc/nginx/naxsi.rules
}
location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;   
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
}   

}
