ISP with nginx: Pages from another domain

Hi,
I changed the web server for a few months, going from apache2 to ngnix (new installation).

I noticed that pages from another domain, simple html pages, are displayed on another domain (wordpress installed).

In particular, I see them on the domain where I have installed wordpress and not vice versa.

I think the problem is in the only configuration that I have entered on "nginx Directives", of which I am reporting the configuration.

Code:

location / {
    try_files $uri $uri/ /index.php?$args;
}
location /wp-admin/ {
    try_files $uri $uri/ /index.php?$args;
    auth_basic "Amministrazione";
    auth_basic_user_file /var/www/clients/client1/web14/web/.htpasswd;
}
location /wp-admin/admin-ajax.php {
    allow all;
}

To be precise, I see the "page.html" page of the first site, on the site where there is wordpress and not vice versa.
example:
site.com/contatti.html (correct)
sitewp.com/contatti.html (Not correct because this page belongs to "site.com")

 

sorry
