Re: network error: software caused connection abort
I'm also facing the issue, using C# on Windows10 and I have added proxy aswell to connect external server(sftp).
Thanks for your report.
Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
You will find my address (if you log in) in my forum profile.
