Getting Internal Server Error when i use nginx config

I tried to use nginx config from https://codeigniter4.github.io/userguide...ight=nginx

i am getting internal server error on args.

For example www.example.com/home/test

I changed that example with 

PHP Code:

location / {
try_files $uri $uri/ /index.php$args; 
} 


dropped just one / and now it's working...
