Can Nginx configure a 404 page to correspond to multiple domain names?

Question

Such as the title: There is only one server in nginx, and all domain names are configured the same. Through program differentiation, each domain name is an independent site. I want each domain name to display its corresponding 404 page when 404 occurs. I don’t know how to configure it under nginx. {code...}

Just move the following to the http scope. Don’t write one in each server
error_page 404 /404.html;

If you encounter this kind of problem, you should read the documentation:
Syntax: error_page code ... [=[response]] uri;
Default: —
Context: http, server, location, if in location

context represents the scope of this error_page syntax, indicating that it can be placed in http.

Try map

//context http

map $http_host $page {
    default  404.html;
    .com   404.com.html;
    .cn 404.cn.html;

}

//context server

error_page $page;
