Wrong answer for incorrect subdomains

[bartlebi]

If there is no record of a subdomain on the server and when directed to it from the DNS zone, for some reason the server returns the page
Success!
Your new web server is ready to use.
with the response code 200.
Is this the correct behavior? Shouldn’t the server return a response with the code 404 in this case or 500? Where can I fix this behavior?

We just load /var/www/html page and nothing more. We don’t provide any config option for it.

Personally the number of hits are usually really minimal…

You can customize the content of the index.html file in the /var/www/html directory.

You do not need to change the file name. Otherwise, an error will occur. Only the content of the file will be updated.

@eris Thank you for your reply. Yes, the problem does not occur in everyday life, but it is important for removing old subdomains from search engines.
@yunli Yes, thank you. However, I am more interested in the server response code in this case, which is 200, and I would like to change it to 500 or at least 404. Is there a way to do this?

Do you want to test the problem? Just access a non-existent file or folder. For example, your server IP: 21.1.2.3/123/1
If you want to check whether the website you deployed is normal, please provide the website domain name. The IP method only supports checking whether hestia is running normally on your server. Hestia only supports domain name work

This is not exactly what you are talking about. Yes, if I request a file that does not exist on the server, I will get a 404 error - this is expected behavior and there is no problem here.
However, if I have a record in DNS about directing the domain to the address of the server with HestiaCP, then in case of a request for the root of the site, I will get the above response - your web server is ready and the response code will be 200.
Of course, if I make a request subdomain.domain.com/blablabla.html - the response will be 404, but with a root request subdomain.domain.com/ - the response will be 200.
And the question is how exactly to change the response code for the
“root” request, which is returned just when the index.html page is returned in the /var/www/html directory.

You can just edit /etc/nginx/conf.d/ip.conf (replace ip with server ip)

And replace:

location / {
		root /var/www/html;

                return 404;
		location /error/ {
			alias /var/www/document_errors/;
		}
	}
