Laravel Valet returns 404 error not found over local network

Question

I'm basically trying to run my Laravel installation over laravel valet through Local Network sharing. I've followed the steps described on: https://laravel.com/docs/9.x/valet#sharing-sites-on-your-local-network

However, I'm still having a 404 - not found when trying to access my website over "192.168.31.166/my-app.test".

I tried both with and without HTTPS Certificate and still got the same error. I can access the website from: my-app.test but not from 127.0.0.1/my-app.test nor from 192.168.31.166/my-app.test

Here is my valet.config file (I deliberately changed my username to USERNAME as it includes my real name):

server {
    listen 80 default_server;
    #listen VALET_LOOPBACK:80; # valet loopback
    root /;
    charset utf-8;
    client_max_body_size 128M;

    location /41c270e4-5535-4daa-b23e-c269744c2f45/ {
        internal;
        alias /;
        try_files $uri $uri/;
    }

    location / {
        rewrite ^ "/Users/USERNAME/.composer/vendor/laravel/valet/server.php" last;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log "/Users/USERNAME/.config/valet/Log/nginx-error.log";

    error_page 404 "/Users/USERNAME/.composer/vendor/laravel/valet/server.php";

    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass "unix:/Users/USERNAME/.config/valet/valet.sock";
        fastcgi_index "/Users/USERNAME/.composer/vendor/laravel/valet/server.php";
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME "/Users/USERNAME/.composer/vendor/laravel/valet/server.php";
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }

    location ~ /\.ht {
        deny all;
    }
}

You need to add domain and your server IP to /etc/hosts first

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
#this is your installed valvet server local IP
192.168.31.166  my-app.test 

and then you can access from another device with my-app.test domain.
