unable to access php file nginx - php

Question

I am completely new to nginx .
I have project based on angular js which have a index.html, and on a certain event i perform a angular http request to x.php file and fetches the response from it.
Its running perfect on my local system and a apache based private hosting server.
I created a free tier ec2 instance and started a centos based linux instance on which i hosted the code and installed nginx .
Here is my nginx config
server {
listen 80;
server_name mydomain.co.in www.mydomain.co.in;
location / {
root /var/www/html/indm;
index index.php index.html index.htm;
try_files $uri/ $uri /index.php?$query_string =404;
}
location ~ \.php$ {
try_files $uri $uri/ /index.php?q=$uri&$args =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
add_header Access-Control-Allow-Origin *;
proxy_set_header Access-Control-Allow-Origin $http_origin;
}
error_page 500 502 503 504 /50x.html;
At first it was giving me 500 gateway error when the http request was performed on that php file. I check in the XHR request.Here is the error in nginx error.log
[error] 17193#0: *2 rewrite or internal redirection cycle while internally redirecting to "/index.php", client: 42.111.38.254
I searched a bit and changed appended a "=404" to try uri statement. But now it redirect to a 404 . I want to run that php file.
the server
Nginx server is running
php fpm is also running
Please help

The location ~ \.php$ block has no root. Move the root statement into the server block so that the same value is inherited by both location blocks.
For example:
server {
...
root /var/www/html/indm;
location / {
...
}
location ~ \.php$ {
...
}
...
}
