I am using WinSCP for a web development class in school. I have been using it for 2 months no problems, but today every time I try to login I get the error server unexpectedly closed network connection. I have looked a FAQ but don't understand where to go because I have not much experience with using the product. I am trying to connect to the school's server from home but it is not letting me. But if I am at school I can connect to the server. Can anyone please help me??
