2 domains on the same IP do not work?

Question

Nginx

listen 80;
listen[::]:80;
server_name WebsiteNumberOne.com Somedomain.net;
set $base /home/somesite;
root $base/html;

this is the last config i tried.
I also tried to separate them into separate configs, somedomain.net still refuses to work, ERR_CONNECTION_REFUSED error.

rebooted configs, did tracing, the domain leads to IP everything is smooth.
the server refuses to accept connections on the second domain, what's the problem?

Answer 1

I would still double-check the DNS.
What does
wget WebsiteNumberOne.com
and
wget Somedomain.net give
?

Answer 2

What are the entries in localhost?
