I solved it by simply add the /certificate switch. Now all is fine.
I have trouble with WinScp. All I wanna do is to load a file up via Winscp.
I estabblished a connection and than I let WScp generate the script.
But everytime I startet the script, I got the option to acceppt the certifcate or not. If nothing done, the transfer breaks up. Always pressing yes is annoying. Is there a way to stop the options or to silence it or to make yes to default option?
