Ошибка при попытке скопировать файлы w/scp

Я соединяюсь с экземпляром Ubuntu, запуская некоторые тесты Apache/JMeter, и пытаясь использовать scp для захвата файлов журнала от упомянутых тестов.

Я соединяю w/следующая команда:

ssh my-host.amazonaws.com -l my-username

Я могу соединиться, и я могу запустить тесты. Однако я должен все же выполнить команду scp без ошибки.

Я использую следующую команду:

scp my-username@my-machine-address.amazonaws.com:~/my-file-name.jtl ./

Я сразу получаю следующую ошибку:

Permission denied (publickey).

Какая-либо идея, какова проблема могла быть? Я имею права соединиться с машиной во-первых. Кроме того, имя пользователя "моего-имени-пользователя" совместно используется парой проверочных пользователей, и другие могут выполнить команду scp без проблемы.

Править: вот мой вывод от попытки scp, управляют w/-v аргумент:

my-username@ip-xx-xx-xxx-xx:~$ scp -v 
    my-username@my-host.amazonaws.com:/home/ubuntu/jmeter.log ./
Executing: program /usr/bin/ssh host my-host.amazonaws.com, 
    user ubuntu, command scp -v -f /home/ubuntu/jmeter.log
