Image are not displayed from public folder

Hey I'm using some placeholder image files, and for most of the projects it always works like expected, but I started recently a new project and wanted to integrate a few placeholder images, but suddenly they are not working anymore... I don't know if that is an error on the site configuration in Nginx or not... because I tried a lot and just copied it 1-1 like in other projects, and it's not working. The only difference is this time it's Inertia with Laravel 10... I had also Inertia Projects some time ago and there was also no problem...

Also, I'm using FF as a Browser, and throws the error "NS_ERROR_NET_PARTIAL_TRANSFER", so could it maybe be because I'm on my local machine and only have "HTTP" and not "HTTPS"?

But like I said for other projects it's still working even with "HTTP".

My Nginx site config looks like that.

server {
        listen 80;
        listen [::]:80;
        server_name _;
        root /var/www/html/public;
        index index.php index.html;
        location / {
                try_files $uri $uri/ /index.php?$args;
        }
        location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/run/php/php8.3-fpm.sock;
        fastcgi_buffers 16 16k;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        }
}

Thanks for any help :)
