I am seeing this error appear when the masternode is attempting to replicate to the other storage nodes. As far as I can tell it is not an issue with passwords or permissions. I am running the most current version of fog on ubuntu 14.04.

Try to ssh into your stroage nodes using the same username and password for the storage node in Storage Management --> <select node>–> Management Username & Management Password. This will confirm that the password info is correct. As a reminder certain browsers will prefill info so make sure to disable prefill for your browser when looking at this information.
I have, and it has not resolved the issue.
Have you tried restarting the FOGImageReplicator service?
