Отказано в доступе, когда я пытаюсь SSH на сервер

У меня возникла проблема, когда я пытаюсь подключиться к серверу с помощью закрытого ключа RSA. Я получаю сообщение об ошибке «Отказано в доступе», за которым следует «Слишком много ошибок аутентификации для [пользователя]».

Примечание. Ключ rsa id_linux имеет разрешения 600.

Вот вывод оболочки:

Вот как выглядит мой файл ssh_config.

Host comics HostName [site] IdentityFile ~/Desktop/Storage/id_linux IdentitiesOnly yes PubkeyAuthentication yes User [user] Port 2222 

Я пытался создать новый ключ, но это не сработало. У меня все еще та же проблема.

Спасибо за вашу помощь!

РЕДАКТИРОВАТЬ: Вот заголовок ключа.

-----BEGIN RSA PRIVATE KEY----- Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,A9C39F2105CA158B 

РЕДАКТИРОВАТЬ 2: Вот вывод комиксов ssh -vvv. Примечание: я использую putty для доступа к машине с Linux, с которой я работаю. Кроме того, я создал новый ключ, чтобы убедиться, что я использовал правильную фразу-пароль.
