Laravel Auth not working after moving to remove - laravel

Question

I have moved my local laravel Application to Production. On my local pc the register function work's well (using Laravel Auth). On the remote host nothing happeds when I submit the register form. No validation error or something else. What is wrong with my application?
I got an 404 while the process. Here my register routes:
Route::get('register', 'Auth\RegisterController#showRegistrationForm')->name('register');
Route::post('register', 'Auth\RegisterController#register');
Here the content of my register.blade.php file:
<form id="js-validation-signup" action="{{ route('register') }}" method="post">

Answer 1

I think i had the same problem with login here.
my problem was that I used Laravel's auth login and inside Auth/LoginController has a
use AuthenticatesUsers which uses a trait that is inside vendor and Auth folder and when I wanted to use git clone to get the project on another computer and used composer install to install the used packages for the project my vendor changed to default and all the login code which was in AuthenticatesUsers trait removed and changed to default

The route() function is for named routes.
It seems that you named your get route but didn't do that with the corresponding post route. Accessing route('register') with a POST method will result in a 404 error.
Try to name the post route as well or use action('Auth\RegisterController#register')
<form id="js-validation-signup" action="{{action('Auth\RegisterController#register')}}" method="post">
