I have an application that sends and receives data using the Internet Transfer control in Visual Basic .NET. At the moment it simply uses port 80 and icHTTP protocol to communicate with the server. However, I need to encrypt the data using SSL. I have tried changing the protocol to icHTTPs (port 443) but it won't respond. I have tested SSL connectivity on the webserver through a browser and everything is working fine. Does anyone know what might be causing the problem?
