Отказано в доступе, когда я пытаюсь SSH на сервер

У меня проблема, когда я пытаюсь подключиться к моему серверу с помощью закрытого ключа RSA. Я получаю ошибку «Отказано в доступе», за которой 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 ключевой заголовок.

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

EDIT2: Вот вывод комиксов ssh -vvv. Примечание: я использую putty для доступа к Linux-машине, с которой я работаю. Кроме того, я создал новый ключ, чтобы убедиться, что я использовал правильную фразу-пароль.
