Angular 4 + Laravel 5 Error: The resource you are looking for has been removed, has its name changed, or is temporarily unavailable

I have a project in which I am using Angular 4 and Laravel 5.

Locally it is running locally but when I go into production (I'm using Azure as the server) it does not work properly.

I have a registration form and Angular. And clicking the "register" button will execute this method:

onSubmit(form){
    console.log(form.value);
    this.http.post('/api/register', (form.value))
        .map(dados => dados)
        .subscribe(dados => console.log(dados));
  }

This method sends the data to the Laravel api route (api.php):

Route::post('/register', 'UserController@store');

Locally, when I run the application via "php artisan serves" command, it works perfectly. But when I went into production, the console reported this error when I clicked the "register" button:

"The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."

It is trying to access the URL / api / register but this url does not really exist.

Locally it recognizes, but in production does not work. How can I resolve or circumvent this error?
