Platform: debian 12.6 "bookworm", amd64
nginx 1.22.1
I have the following in /etc/nginx/sites-available/default:
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
return 444;
}
This succeeds in some requests using just the IP number returning 444
(which is what I want).
But most of the IP number requests returns 404.
Some IP number requests returns 200 OK.
Does anyone have an idea why?
Here's an extract from the /var/log/nginx/access.log. with requests
using the IPv4 IP number of the server (starts out with a 200, then
comes a couple of 444 (which is what I want), then a couple of 200,
responses, and then some 444 responses, then 200, then 404, then some
444 adresses again until all starts to return 404 (server's IP address
has been replaced by "<server's IPv4 address>"):
