Re: Cannot connect using FTPS with TLS Explicit Encryption

WinSCP uses FTP implementation from Filezilla. So it may possibly suffer the same issues.

What I find strange is that you connect to 990 port (port for implicit FTPS), yet you have explicit FTPS configured.

Cannot connect using FTPS with TLS Explicit Encryption

Hi there,

First off, big thank you for implementing FTPS. I am forced to use it, and I didn't feel like dropping my favourite file transfer program :wink:

However, I am not able to connect to the server, and I don't know why. The admin says that FileZilla has FTPS implemented wrong and recommends using coreFTP instead. Could WinSCP have the same problem?

I have tested the same settings on WinSCP and coreFTP, and the former fails (AUTH not understood), while the second connects successfully (although slooooooooowly).

Any help is appreciated. I attach the debug output, in case it helps (some private data removed).

THANKS!
