I don’t see python on your image :)

I wanted to have a default server that catch ~wrong DNS query to the server

server {
    listen 443 ssl;
    server_name _;
    ssl_certificate /etc/nginx/ssl/catchall.crt;
    ssl_certificate_key /etc/nginx/ssl/catchall.key;

    error_page 404 /404_CatchAll.html;

    # Everything is a 404
    location / {
        return 404;
    }

    location /404_CatchAll.html {root /var/www/html/;}
}

The full working code:

server {
    listen 443 ssl;
    server_name _;
    ssl_certificate /etc/nginx/ssl/catchall.crt;
    ssl_certificate_key /etc/nginx/ssl/catchall.key;

    error_page 404 /404_CatchAll.html;

    # Everything is a 404
    location / {
        return 404;
    }

    location /404_CatchAll.html {root /var/www/html/;}
}

ok I’ve found something that ~works !

	server {
		listen 443 ssl;
		server_name _;
		ssl_certificate /etc/nginx/ssl/catchall.crt;
		ssl_certificate_key /etc/nginx/ssl/catchall.key;

		error_page 404 /404.html; #at /var/www/html/

		location /404.html {internal;}

		return 404;
	}

so i get the default 404 html from nginx. but not the one that I specified error_page 404 /404.html; any ideas ?

line 5 you mean ?

error_page 404 /404.html; #this one ?
