Отказано в аутентификации с открытым ключом SSH

Я пытаюсь подключиться к виртуальной машине через SSH.

Я могу войти в учетную запись с пароль.

Я создал другого пользователя без пароля, сгенерировал ssh-ключ на моем хост-компьютере (Windows),и поместил открытый ключ в пользовательский / .ssh / authorized_keys и установил разрешение только на чтение с полным владением пользователем.

Однако, когда я пытаюсь использовать ssh, с локального хоста на виртуальной машине ИЛИ с моей хост-машины , открытый ключ всегда запрещен. Я настроил ssh-сервер так, чтобы он принимал только аутентификацию с открытым ключом.

Это ошибка, которую я получаю при запуске ssh -vv user @ localhost -i privatekey

PS C:\Users\gicum\.ssh> ssh -vv mironica@192.168.230.129 -p 2222 -i mironica

Проблема аналогична при попытке через localhost как упомянутое выше. Я не могу понять, в чем может быть моя проблема?
