Re: Network error: Connection timed out
Please attach a full session log file showing the problem (using the latest version of WinSCP).
Though, in genera, the operating system can choose to timeout sooner. How long does the connection take, when it works?
You can also consider simply retrying the script:

To generate the session 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.
