Filter and Pagination

Hi guys, i make a filter and it works but when i try to access to the second page of the filter response with 404 error

This is my filter function at the controller

public function filtrar(Request $request)
    {

        $reportes = Reporte::whereYear('created_at', '=', $request->input("año"))
                    ->whereMonth('created_at', '=', $request->input("mes"))
                    ->orderBy('created_at', 'asc')
                    ->paginate(8);

        $reporteEmpleados = Reporte::whereYear('created_at', '=', $request->input("año"))
                            ->whereMonth('created_at', '=', $request->input("mes"))
                            ->orderBy('created_at', 'asc')
                            ->paginate(8);

        return view('reportes.filtro', compact('reportes', 'reporteEmpleados'));

    }

​

And this is my view

@extends('adminlte::page')
@section('htmlheader_title', 'Todos los reportes')
@section('contentheader_title', 'Todos los reportes')
@section('main-content')
<a href="/reportes/create" class="btn btn-success">Redactar un nuevo informe <i class='fa fa-pencil'></i></a>
<nav aria-label="breadcrumb">

        </tr>
    @endforeach
  </tbody>
</table>
</div>
{{ $reportes->appends('reportes')->links() }}
@endcan
@endsection
