When I uncheck "The connection is in test-mode" and I set "secure=true" in the default.aspx.cs, my connection fails. Any thoughts where the issue may be coming from? I can't seem to find the disconnect.
jsConnect signs its data with a hash for security. This is most likely what's failing on your end. I just updated the jsConnectdotNet library so I'd first try updating jsConnect.cs from that.
