page not opening when click the post – Laravel

When I click my ticket it is not opening the specified page. While clicking the link of my ticket it shows in the link the correct ticket id, but the page is not opening. The error is:

404 not found

Ticket.blade.php

<tr>
  @foreach ($ticketsinfos as $ticketinfo)
  <td>IR-173049</td>
  <td>Dito</td> 
  <td>{{ $ticketinfo->companies->name }}</td>
  <td><a href="/tickets/show/{{ $ticketinfo->id }}">{{ Str::limit($ticketinfo->ticket_title, 50, '...') }}</a></td>
  <td><button class="btn btn-danger btn-sm" type="button">Action Needed<br></button><br></td>
  <td>Tako Kiknadze</td>
  <td>{{ $ticketinfo->created_at }}</td>
  <td>{{ $ticketinfo->updated_at }}</td>
  </tr>

  @endforeach  
</tr>

web.php

Route::get('/', function () {
    return view('welcome');
});

Route::resource('/dashboard', DashboardController::class);

Route::resource('/tickets', TicketsController::class);

Route::resource('/admin/users', AdminsUserController::class);
// Route::resource('/companies', CompaniesController::class);

Auth::routes();

Route::get('/home', [AppHttpControllersHomeController::class, 'index'])->name('home');

Controller

public function show(Tickets $tickets)
{
  $tickets = Companies::with('tickets')->get();
  $severities = Severities::with('severity')->get();
  $ticketsinfos = Tickets::with('companies')->findOrFail(2);
  return view('customer.index', compact($tickets))->with(['tickets' => $tickets])->with(['severities' => $severities])->with(['ticketsinfos' => $ticketsinfos]);

  //dd($ticketsinfos->toArray());
}

When I use ‘dd’ it works.
