Резервные копии не записываются в S3, когда IMDSv1 отключен, а настройка «s3 use iam profile» включена.
В соответствии с внутренними требованиями безопасности мы отключили использование IMDSv1 на экземпляре EC2, на котором размещена наша установка Discourse. Это приводит к ошибке в процессе резервного копирования при загрузке архива в S3.
