FTP – WSAECONNRESET An existing connection was forcibly closed by the remote host.
One of the most common problems with FTP data transfers (including downloading directory listings) has to do with Passive vs. Active mode.

Normally, if you choose the mode that doesn’t work, the data connection is blocked […]

Understanding SFTP Absolute FilePaths
