nginx serving wrong certificate for another domain?

Reported by: Lorenzo Raffio Owned by:
Priority: minor Milestone:
Component: nginx-core Version: 1.7.x
Keywords: ssl certificate sni Cc:
uname -a:
nginx -V: 1.7.4


I have SNI installed and running fine. I have 6 websites hosted on the same VPS, same IP. 5 of them work just fine, every one is serving its correct ssl certificate.
But there's one that even if I'm setting ssl_certificate to the correct crt file related to that domain, is serving the certificate of another domain! (WTF?)

Here's the whole conf file for this domain:

fastcgi_cache_path			/var/www/ levels=1:2 inactive=60m;

server {

	### MAIN ###

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

	ssl_stapling				on;
	ssl_stapling_verify			on;
	ssl_trusted_certificate			/var/www/;
	ssl_certificate				/var/www/;
	ssl_certificate_key			/var/www/;
	access_log				/var/www/ combined gzip;
	error_log				/var/www/;
	charset					utf-8;
	rewrite					^/sitemap_index\.xml$ /index.php?sitemap=1 last;
	rewrite					^/([^/]+?)-sitemap([0-9]+)?\.xml$ /index.php?sitemap=$1&sitemap_n=$2 last;
	location / {
		try_files $uri $uri/ /index.php?$args;

	location ~ \.php$ {
		fastcgi_cache_valid 200 5m;	
		fastcgi_cache_bypass $no_cache;
		fastcgi_no_cache $no_cache;
		try_files $uri =404;
		fastcgi_split_path_info ^(.+\.php)(/.+)$;			
		include fastcgi.conf;
		fastcgi_pass unix:/var/run/php5-fpm.sock;

	### CONFIGS ###
	include conf/h5bp.conf;
	include	conf/expires.conf;

	### TRIVIAL ###

	# Deny dot files:
	location ~ /\. {
		deny all;

	# favicon.ico not found
	location = /favicon.ico {
		access_log off;
		log_not_found off;

	# robots.txt not found
	location = /robots.txt { 
		access_log off; 
		log_not_found off; 

	### CACHE ###

	#Cache everything by default
	set $no_cache 0;

	#Don't cache POST requests
	if ($request_method = POST)
	    set $no_cache 1;

	#Don't cache if the URL contains a query string
	if ($query_string != "")
	    set $no_cache 1;

	#Don't cache the following URLs
	if ($request_uri ~* "(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)")
	    set $no_cache 1;

	#Don't cache if there is a cookie called PHPSESSID
	if ($http_cookie ~* "PHPSESSID|comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in")
	    set $no_cache 1;

Don't know if useful but I also add general nginx config.

And one other strange thing is that when for example I got to my wordpress login page over https and enter my login details, I'm redirected to the domain of the wrong certificate. Maybe is Strict Transport Security involved?

Don't consider the Cloudflare related parameters. It's disabled for the domain.

Resolution: invalid
Status: newclosed

The server{} block in question doesn't have any listen directives in it, and hence will use listen 80 by default. It's not expected to be used for https requests, as https use port 443.
