Сегодня у меня возникла проблема, из-за которой я больше не мог подключиться к своему экземпляру EC2, используя учетную запись ec2-user по умолчанию. Мой ключ просто отклонен.
Странно то, что я не изменил свой закрытый ключ. Более того, я могу подключиться как «root», за которым следует приглашение использовать учетную запись «ec2-user».
Есть ли способ обойти эту проблему? Кто-нибудь сталкивался с такой проблемой? Вот мой ssh -v вывод:
