I am getting the above error when using FTP in VB6. I have tried all combinations of ftp.Passive, ftp.AuthTls, ftp.Ssl. ftp.Passive=0 seems to allow me to get further than other combinations. When I run FTP in the command line, I can upload a file successfully, but the code in a VB6 exe fails on the ftp.AsyncPutFileStart command with the above response. Can you help?

Can you post a code sample?

Also, post the contents of the LastErrorText property as they exist immediately after the failing call - there might be useful information there.

sorry this is not showing as I posted it - it seems to have lost line feeds

You need to put your logs in <pre> </pre> tags for the formatting to be preserved.

If you do some searching on FTP error 425, it seems like it's usually an issue with the application being blocked by a firewall (software and/or hardware). There are a number of forum posts at other forums on how to resolve this issue, so I would try those first and see if you make any progress.
