[Nginx] Subdomain automatically loads another domain

I have ISPConfig 3.0.4.6 and Ningx installed in my server, I have created a subdomain in a domain A but this subdomains loads the webpage in domain B, I have try to find why, but I couldn't find any answer, here you have the two vhosts:

Code:

server {
        listen 91.121.163.140:80;
		
        
        server_name a.mthweb.org ;

        root   /var/www/a.mthweb.org/web;
		
		
		
        index index.html index.htm index.php index.cgi index.pl index.xhtml;
		

		
        error_page 400 /error/400.html;
        error_page 401 /error/401.html;
        error_page 403 /error/403.html;
        error_page 404 /error/404.html;
        error_page 405 /error/405.html;
        error_page 500 /error/500.html;
        error_page 502 /error/502.html;
        error_page 503 /error/503.html;
        recursive_error_pages on;
        location = /error/400.html {
            internal;
        }
        location = /error/401.html {
            internal;
        }
        location = /error/403.html {
            internal;
        }
        location = /error/404.html {
            internal;
        }
        location = /error/405.html {
            internal;
        }
        location = /error/500.html {
            internal;
        }
        location = /error/502.html {
            internal;
        }
        location = /error/503.html {
            internal;
        }
		
        error_log /var/log/ispconfig/httpd/a.mthweb.org/error.log;
        access_log /var/log/ispconfig/httpd/a.mthweb.org/access.log combined;

As you can check first vhost loads the second vhost, but they have nothing in common, except the IP, but it is the server IP.

Note: Two domains belong to the same client, other clients don't happen.

 

And the subdomain is listed in the server_name line? Maybe you made a small typo somewhere.

 

You have here the full host files, I didn't remove anything, they are the default files generated by ISPConfig
