SFTP using PuttyGen

Neuron 3.0.3.336

We are using Puttygen with no passphrase.  Key gets rejected by server.

Puttygen generated key with no passphrase,  I use a tool called WINSCP to test my connection which works perfect.  I have putty gen with passphrase on another adapter in Neuron for another vendor and works great. Log Files attached.
