Ok, in that case I prefer to run the old version until my FTP server provider upgrades its encryption algorithms. Otherwise I could get a lot of problems trying to 'patch' with special configurations.

Thank you very much.

Please post logs from both versions. Chances are that your FTP server uses an obsolete encryption algorithms that the latest version of WinSCP either does not support anymore and does not allow by default unless configured otherwise.

When I try to connect to usual and saved FTP server, as always, the connection fails over and over. I have to use this connection every Day, and I cannot to risk several days without connection trying to solve an app problem.

Thank you to answer!

What does not work? Can you please be more specific?

Hi there,

Why they launch a new version of WinSCP 6.3.4 and they insist every time we open the app to upgrade if it does not work? I do not have time to investigate and work trying to solve the problems of new versions.

Thank you
