php - Error with mysqli->prepare - Malformed communication packet

one text

My code was working fine, but today I am getting this error using mysqli-prepare "Malformed communication packet"

Code:

<?php
  require_once('conntele.php');
  $sql_type = "SELECT id_tipo_identificacion, descripcion FROM tipo_identificacion WHERE estado_registro = 'A'";
  echo "Using Mysqli->query<br>";
  if ($res_type = $mysqli->query($sql_type)) {
    while($row_type = $res_type->fetch_assoc()){
      echo "type: ".$row_type['id_tipo_identificacion']." description: ".$row_type['descripcion']."<br>";
    }
  }

  echo "<br>";
  echo "Using Mysqli->prepare<br>";
  if ($stmt = $mysqli->prepare($sql_type)) {
    $stmt->execute();
    $result_type = $stmt->get_result();
    print_r($stmt);
    while($row_type_iden = $result_type->fetch_assoc()){
      echo "type: ".$row_type_iden['id_tipo_identificacion']." description: ".$row_type_iden['descripcion']."<br>";
    }
    $stmt->close();
  }

  $mysqli->close();
?>

Error:
