14.04 - Error when attempting to copy files w/ scp - Ask Ubuntu

i'm connecting ubunto instance, running apache/jmeter tests, , attempting use scp grab log files said tests.

i connect w/ following command:

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

i'm able connect, , i'm able run tests. however, i've yet perform scp command without error.

i'm using following command:

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

i following error:

permission denied (publickey). 

any idea issue be? have rights connect machine in first place. also, "my-username" username shared couple test users, , others able perform scp command without issue.

edit: here output attempting scp command w/ -v argument:

you not running both commands same machine or same user.

one output says /home/ubuntu/.ssh/id_rsa used, other says /c/users/jdoe/.ssh/id_rsa

so using wrong key in scp case, coming wrong directory.
