paramiko.AuthenticationException: Authentication failed. in distributed mode

[ramonasuciu]

I have encountered this problem when trying to run tests in distributed mode.
The Funkload version I am using is 1.17.0.

The error I get is:

Traceback (most recent call last):
  File "/Users/rsuciu/Documents/work/dev_tests/tests_funkload/newf/bin/fl-run-bench", line 8, in <module>

paramiko.AuthenticationException: Authentication failed.

Do you know why this might be happening?

Thanks,
