enable hotlinking to images css not working

I am trying to figure out how to enable hotlinking on my site in nginx but it doesn’t seem to be working. Here is the code for my configuration. I don’t want people direct access to .mp3 .jpg

Here is the code below for the configuration

include forge-conf/mydomain.com/before/*;

server {
    listen 80;
    listen [::]:80;
    server_name mydomain.com;
    root /home/forge/mydomain.com/public;

    # FORGE SSL (DO NOT REMOVE!)
    # ssl_certificate;
    # ssl_certificate_key;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
       ssl_prefer_server_ciphers on;
    ssl_dhparam /etc/nginx/dhparams.pem;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.html index.htm index.php;

    charset utf-8;

    # FORGE CONFIG (DOT NOT REMOVE!)
    include forge-conf/mydomain.com/server/*;

   location / {
       try_files $uri $uri/ /index.php?$query_string;
}
    
    
    

    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  /var/log/nginx/mydomain.com-error.log error;

    error_page 404 /index.php;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }
    
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;

    }
    
    #Prevent hotlinking
location ~* (\.jpg|\.png|\.css|\.mp3)$ {
    valid_referers blocked mydomain.com www.mydomain.com;
    if ($invalid_referer) {
        return 444;
    }
}


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