laravel MethodNotAllowedHttpException when do POST on online server

I have got MethodNotAllowedHttpException when running on online server, but on local server it runs well.

The PHP version is same, the method is used POST. The other POST methods are runs well except this one.

on blade.php

<form action="{{ route('update.product') }}" method="POST" enctype="multipart/form-data" class="form-horizontal js-form">

on routes/web.php

Route::post('/updateProduct', [
   'uses' => 'AdminController@updateProducts',
   'as' => 'update.product'
]);

#php #laravel
