Я установил новый рабочий узел 1.16.0, используя kubeadm, и получаю следующее:

Не очень забавно то, что все остальные узлы имеют абсолютноНЕТ проблем с созданием куб-прокси. Это только один узел, который выходит из строя с вышеуказанной ошибкой.
Я пытался решить эту проблему разными способами, но пока не нашел решения. Предыдущие установки, использующие kubeadm, были безупречны.
У меня такое ощущение, что мне не хватает PodSecurityPolicy и привязки к роли kube-proxy. Я определенно что-то упускаю, но понятия не имею.
