nginx 504 Gateway Time-out: Adding custom config to laravel recipe to resolve

Question

I'm using lando for development and it's working fine until I run this code:

Route::get('/test', function(){
    set_time_limit(600);

    for($i=0; $i<250; $i++){
        echo $i;
        sleep(1);
    }
});

it gave me this error: 504 Gateway Time-out nginx

Then I checked this doc https://docs.lando.dev/nginx/config.html and this is how my .lando.yml file looks like:

name: test
keys: false
recipe: laravel
config:
  php: "7.4"
  via: nginx:1.18
  composer_version: 2.0.8
  database: mariadb:10.4.17
  webroot: ./public
  cache: redis
  server: nginx.conf

proxy:
  appserver_nginx:
    - admin.test
    - admin.test.lndo.site
services:
  appserver_nginx:
    run_as_root:
      - ln -snf /usr/share/zoneinfo/America/Denver /etc/localtime
      - echo "UTC" > /etc/timezone
  db_gui:
    type: phpmyadmin

Here is my nginx.conf:

            request_terminate_timeout = 600;
        }
    }
}

I then run lando rebuild but still I'm facing the same issue.
