Laravel route works perfectly locally but not on remote. (Dingo Api)

I am using dingo/api for a project and all of my routes work other than 1.

routes.php

    $api = app('api.router');
    $api->version('v1',['prefix' => 'api'], function ($api) {

        $api->post('users', "App\Http\Controllers\Auth\UsersController@store");
...
        });

store method :

/**
     *
     * @param  \App\Http\Requests\Auth\StoreUserRequest  $request
     * @return \Illuminate\Http\Response
     */
    public function store(StoreUserRequest $request)
    {
        if( ! $this->isAdminRequest() )
        {
            return $this->dispatch(new RegisterUserCommand($request));
        }
    }

This route throws 405 Method Not Allowed Exception.

php artisan api:routes shows that it is registered, both locally and on server. I am using POSTMAN to test my api and have all required fields. In response I do get Allow : POST.

NOTE :

• There are other post routes that work perfectly.
• There are other UsersController routes that work perfectly
• I have tried removing all other routes and with just this, it still does not work.

Any help is appreciated. Thanks.
