I'm attempting to upload to an FTP site with TLS enabled. I can connect fine but the PutFile fails. I have checked with our sysadmin on the settings and he confirmed I have them right but unfamiliar with the error.

FTP2.AuthTls = True
FTP2.Ssl = True
FTP2.Passive = True
FTP2.SslProtocol = "default"
Ftp2.Port = 21

This uses an old version of Chilkat. Always test first with the latest version to see whether the problem remains, or if it manifests differently. Also, notice that the protocol here is "SSL 3.0". The latest version of Chilkat will most certainly use "TLS 1.2" by default. This is likely the solution.

I had tried "default", "TLS 1.2 or above" and actually all of the choices listed in the docs and they all gave the same result. I'll get latest and let you know.

Thanks, Catl
