Route not defined in laravel - laravel

Question

I'm getting this error
ErrorException in UrlGenerator.php line 304: Route [customer.signup] not defined. (View: C:\xampp\htdocs\ecomm\app\Modules\Templates\Resources\Views\layouts\public.blade.php) (View: C:\xampp\htdocs\ecomm\app\Modules\Templates\Resources\Views\layouts\public.blade.php)
but as far as I know my routes is all correct.
My public.blade.php
<li class="dropdown">
<i class="fa fa-user" aria-hidden="true"></i> User Management <span class="caret"></span>
<ul class="dropdown-menu">
<li>Sign up</li>
<li>Login</li>
<li role="separator" class="divider"></li>
<li>Logout</li>
</ul>
</li>
my routes
Route::get('/shipping-info', [
'uses' => 'OpenController#shippingInfo',
'as' => 'cart.shippingInfo'
]);
Route::get('/signup', [
'uses' => 'OpenController#signup',
'as' => 'customer.signup'
]);
Route::delete('/product/deleting/{id}', [
'uses' => 'OpenController#deleting',
'as' => 'deleting'
]);
Route::get('/login', [
'uses' => 'OpenController#login',
'as' => 'client.login'
]);
Route::get('/shopping-cart', [
'uses' => 'OpenController#shoppingCart',
'as' => 'cart.shop'
]);
Route::get('/product/update-item/{id}', [
'uses' => 'OpenController#updateProduct',
'as' => 'cart.update'
]);
Route::get('/', [
'uses' => 'OpenController#index',
'as' => 'index',
]);
Route::get('/{id}', 'OpenController#content');
Route::get('gallery/{title}', 'OpenController#galleryCategory');
Route::get('/product/{id}', [
'uses' => 'OpenController#product',
'as' => 'shop.product'
]);
Route::post('/product/update-cart/{id}', [
'uses' => 'OpenController#updateCart',
'as' => 'cart.updateCart'
]);
Route::put('/product/update-qty/{id}', [
'uses' => 'OpenController#newQty',
'as' => 'new.qty'
]);
My signup method in OpenController
public function signup()
{
echo "OpenController Signup";
}

You have to clear your route cache, if you've already run route:cache before:
php artisan route:clear
