Тайм-аут ввода-вывода Helm kubernetes

Попытка использовать helm на моем кластере kubernetes. helm init прошел нормально, но попытка установить или просто helm list выдает эту ошибку.

$ helm list

Я много часов гуглил, и, похоже, ничего не решает проблему. Вот информация о моем кластере:

• Что я пробовал:
  • Перезапуск всех узлов
  • Удаление Calico и переустановка
  • Обновление Calico
  • Установка Helm в пространстве имен «по умолчанию»
  • Удар головой в рабочий стол
