I am trying to connect to an external SFTP. They have our public key and I have the private key which is password protected. I have the credentials set to the sftp username and the password to the private key.
If I set the private key only, I get a username/password error connecting. If I set both the public and private key files, I get the error below:
ERROR #7510: SSH Error '-19': SSH Error : Callback returned error  at Session.cpp:418,0
