I have a running a Laravel project on Nginx, every thing works fine except when I want to send a POST API, I use Passport for authentication, but when I try to sign up
(or doing any POST request) it returns with 404 and a message "The GET method is not supported for this route. Supported methods: POST.", although it works fine via


php artisan serve

Here is my request:
URL: http://my_droplet_ip/api/v1/sign-up
Body:

{

"first_name":"Nasser_Test",

"last_name":"Ismaiel",

"password":"password",

"email":"abdelnasser.test@gmail.com",

"scode":"School_URL",

"phone":"231564987"

}

The response :

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException: The GET method is not supported for this route. Supported methods: POST. in file /home/nginx/my_project/vendor/laravel/framework/src/Illuminate/Routing/AbstractRouteCollection.php on line 117
