I've recently been getting an SFTP login failure when running my FME workspace.
This was working back in July, but is now throwing the following errors:
FTP info: Trying 'SFTP IP ADDRESS'...
FTP info: Connected to SERVERNAME ('SFTP IP ADDRESS') port 22 (#0)
FTP info: SSH MD5 fingerprint: 'FINGERPRINT'
FTP info: SSH authentication methods available: publickey,gssapi-with-mic,keyboard-interactive,password
FTP info: Failure requesting identities to agent
FTP info: Authentication failure
FTP info: Closing connection 0
FTP/FTPS/SFTP transfer error: Login denied
Now, this I can still connect via my same SSH key using an FTP tool such as WinSCP no problem.
I'm loading the private key via a SystemCaller and the following command beforehand:
Start cmd /c "C:/Program Files/PuTTY/pageant.exe" C:\\PrivateKeys\\PrivateKey.ppk
