Why is the site not opening on nginx?

Question

Nginx

When I try to access a site by domain, I get the error "Unable to access the site." By ip everything is fine.

server {
        listen 80;
        root /var/www/html;
        index index.html;
}

server {
    listen 80;
    server_name <moi_domen> www.<moi_domen>;
    root /var/www/html;
    index index.html;
}

Answer 1

and on the domain at you the direction where goes?
if you come "from outside" then you need to register the ns server on the domain,
if from the local direction, then you need to register the direction of the domain to localhost in hosts
