You server closes connection once it gets your password. You need to ask your server administrator.

Here's my log file...

Thanks so much for responding so quickly. I am now getting a different error, one that I also have not seen before. (ESshFatal) Authentication failed.
What is this?

You domain is probably not known by your DNS server. You should wait several hours or use IP address instead of the domain name.

I just registered a new domain name. When I try to log in via WinSCP, I get the error above. Can you tell me why or what may cause it? And, if you want to be really helpful, maybe tell me how to fix it? :lol:
