cors issue on server but not on localhost

Question

I am working on a laravel 7 project with lighthouse-php as graphQL package.

Everything works fine on localhost but on an Ubuntu 18.04 ec2 nginx server it is giving me CORS issue.

Please Note :- 1) client and server both are on http.

2) my cors.php

return [

    /*

I think your Nginx override the headers add to your Location block the following:

location {
  //...
  add_header 'Access-Control-Allow-Origin' '*';
  add_header 'X-Frame-Options' 'ALLOW-FROM *';
  //...
}
