Re: able to list, delete files, but unable to upload or download any file

Please attach a full log file on Debug 2 log level showing the problem (using the latest version of WinSCP).

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

able to list, delete files, but unable to upload or download any file


I'm using latest WinSCP 5.7.5 GUI and FTPs.
I can connect to my server, view, and delete files.
But when I try to copy any file, WinSCP fails with:

Timeout detected. (control connection)
Copying files from remote side failed.

I and my hosting provided ( suspect that control channel is working fine, but there is an issue negotiating encrypted data channel.

Love WinSCP, but as workaround I currently have to use other ftp client, which does not have this issue.
