Server refused our key: No supported authentication methods available

2025-01-13 03:51

I am calling WinSCP via an SSIS job / bat file, getting an error in the log file telling me the server refused our key. See below for the error.
This is intermittent, sometimes does / doesn't work, I also see the failure when logging in manually using the EXE, hit the reconnect button and it works.
Any suggestions or advice would be appreciated.

Windows 2019
WinSCP 6.3.6
