Любые подсказки? У меня эта ошибка появляется на каждом узле кластера. Имен узлов не менял и ничего подобного. Несколько узлов были обновлены с proxmox 3, несколько — свежие установки. В веб-интерфейсе вижу только форму авторизации. После ввода правильного логина и пароля от сервера нет никакого ответа. В syslog много таких строк:

Пробовал создавать новые сертификаты для pveproxy — не помогло. Нашёл пару похожих тем с такими проблемами, но большинство связаны с изменениями hostname и решения там не дали.

Несколько раз. Всё то же самое.

Так, какие есть идеи, как это поведение починить?

Да, я пробовал разные браузеры. Даже curl использовал. Вот код:

Всё как и должно быть. Добавляю куки для входа. Код:

И всё остальное заканчивается точно так же. Так что, полагаю, дело не в браузерах, а скорее это баг в pveproxy.
