Я изо всех сил старался настроить свой ssh-сервер, хотя каждый раз, когда я пытаюсь войти в систему с авторизацией с открытым ключом, он обнаруживает отказ подписи открытого ключа на сервере, несмотря на принятие ключа.
Я использовал ssh-keygen для генерации пары ключей, а затем загрузил открытый ключ в authorised_keys и отправил закрытый ключ на другой аккаунт и преобразовал его с помощью putty.
К сожалению, я старался изо всех сил, чтобы просмотреть журналы, но ничего не выскакивает, пожалуйста, помогите, если это возможно:

После дальнейшего просмотра вышеуказанного журнала, точка, которая появляется у меня после использования открытого ключа при первом его переносе, а затем после повторной попытки, не работает. У кого-нибудь есть идеи о том, что может вызвать эти откладывания (или возможные сбои)?
