Hello, can anyone help me to hide the port and showing domain only when viewing site from page source ? port only visible if you see it from the page source. screenshot: http://image.prntscr.com/image/59e47f990fa547af9709e9f2a1272834.png

My nginx conf :

code
server {

	listen 443;
	server_name domain.me www.domain.me;

	root /home/kyo/webroot;
	index index.php;

	# SSL
	ssl on;
	ssl_certificate /etc/ssl/cert_chain.crt;
	ssl_certificate_key /etc/ssl/private/domain.me.key;
	
	ssl_session_timeout 5m;
    	ssl_session_cache shared:SSL:50m;

	port_in_redirect off;

	# intermediate configuration.
    	ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    	ssl_prefer_server_ciphers on;
    	ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';

    	# Diffie-Hellman parameter for DHE ciphersuites, recommended 2048 bits
    	ssl_dhparam /etc/ssl/certs/dhparam.pem;

	location / {
	 rewrite /sitemap.xml$ /sitemap.php last;
	 rewrite /feed$ /rss.php last;
	 rewrite ^/go/(.*)$ /go.php?id=$1 last;
	 rewrite ^/view/(.*)$ /page.php?id=$1 last;
	if (!-d $request_filename){
	 set $rule_4 1$rule_4;
	}
	if (!-f $request_filename){
	 set $rule_4 2$rule_4;
	}
	if ($rule_4 = "21"){
	 rewrite ^/mp3/(.*)(\/|\.)(.*)$ /search.php?q=$1&slug=$2 last;
	}
	if (!-d $request_filename){
	 set $rule_5 1$rule_5;
	}
	if (!-f $request_filename){
	 set $rule_5 2$rule_5;
	}
	if ($rule_5 = "21"){
	 rewrite ^/(.*)$ /download.php?po=$1 last;
	}
}

	location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME   $document_root$fastcgi_script_name;

    	expires 1d;
    	add_header Pragma public;

}

	#error_page 404 /404.html;

	# redirect server error pages to the static page /50x.html
	#
	#error_page 500 502 503 504 /50x.html;
	#location = /50x.html {

	#}

	# y access to .htaccess files, if Apache's document root
	# concurs with nginx's one
	
	location ~ /\.ht {
