Nginx listening on various ports - nginx

Question

i have a small issue, i configured various server block with listen directive like below
but i can access toto1.com on port 444 and toto2.com on port 443, but I would prefer if it's was not possible, the listen directive is not only for the server block?
server {
listen 443 ssl http2;
server_name toto1.com;
include /etc/nginx/snippets/ssl.conf;
location /
{
proxy_read_timeout 900;
proxy_pass_header Server;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass https://x.x.x.x;
}
}
server {
listen 444 ssl http2;
server_name toto2.com;
include /etc/nginx/snippets/ssl.conf;
location /
{
proxy_read_timeout 900;
proxy_pass_header Server;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass https://x.x.x.x;
}
}
thanks

you need to create a conf server like that and place it at the begining
server {
include /etc/nginx/snippets/ssl.conf;
server_name titi.com;
listen 444;
listen 443;
return 404 ;
access_log /var/log/nginx/default.access.log main;
error_log /var/log/nginx/default.error.log;
}
