nginx serving wrong certificate for another domain?

Description

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/blabla.it/cache levels=1:2 keys_zone=blabla.it:100m inactive=60m;

server {

		log_not_found off;
	}

	# robots.txt not found
	location = /robots.txt {

	}

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.

comment:3 by Maxim Dounin, 6 years ago

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.

Note: See TracTickets for help on using tickets.
