Fancybox plugin not working with W3 Total Cache

A video in a fancybox not working with w3Tc plugin on nginx. My main conf file for nginx is:

server {

        listen 80;

        root /var/www/xxxxxxx.com;
        index index.php;

        server_name xxxxxxx.com   *.xxxxxxx.com;

        location = /favicon.ico {log_not_found off;access_log off;}
        location = /robots.txt {allow all;log_not_found off;access_log off;}

         include /var/www/xxxxxxxx.com/nginx.conf;

		if (!-e $request_filename) {
                rewrite /wp-admin$ $scheme://$host$uri/ permanent;
                rewrite ^(/[^/]+)?(/wp-.*) $2 last;
                rewrite ^(/[^/]+)?(/.*\.php) $2 last;
        }

        location / {
                try_files $uri $uri/ /index.php?$args /new/index.php?$args;
        }

        location ~ \.php$ {
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
		fastcgi_param SCRIPT_FILENAME /var/www/xxxxxxx.com$fastcgi_script_name;
                include fastcgi_params;
        }

#        location ~* ^.+\.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|rss|atom|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ {
#                access_log off; log_not_found off; expires max;
#        }

}

And my w3Tc nginx file in my wp root is:

# BEGIN W3TC Page Cache cache
location ~ /wp-content/cache/page_enhanced.*html$ {
    add_header Vary Cookie;
}
# END W3TC Page Cache cache
# BEGIN W3TC Page Cache core
set $w3tc_rewrite 1;
if ($request_method = POST) {
    set $w3tc_rewrite 0;
}
if ($query_string != "") {
    set $w3tc_rewrite 0;
}
if ($request_uri !~ \/$) {
    set $w3tc_rewrite 0;
}
if ($http_cookie ~* "(comment_author|wp\-postpass|w3tc_logged_out|wordpress_logged_in|wptouch_switch_toggle)") {
    set $w3tc_rewrite 0;
}
if ($http_cookie ~* "(w3tc_preview)") {
    set $w3tc_rewrite _preview;
}
if (!-f "$document_root/wp-content/cache/page_enhanced/$http_host/$request_uri/_index$w3tc_rewrite.html") {
  set $w3tc_rewrite 0;
}
if ($w3tc_rewrite = 1) {
    rewrite .* "/wp-content/cache/page_enhanced/$http_host/$request_uri/_index$w3tc_rewrite.html" last;
}
# END W3TC Page Cache core
