I installed Nginx server for my laravel project. But css and javascript file not working. Css and javascript file downloadable on server. For example http://myipaddress/css/bootstrap.css download the bootstrap.css file. I call the css file like <link href="{{ URL::asset('css/bootstrap.css') }}" rel="stylesheet"> like this. 
My source code 
My public folder permissions
/etc/nginx/sites-available/default looks like the following
# Default server configuration
#
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
# SSL configuration
#
listen 443 ssl default_server;
listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
