Virtual VP VpConsole Connection Error: Apro exception

I’m having some trouble getting VVP to communicate with my Davis WeatherLink IP data logger. It gives me an error when I click on the connect button in VVP: VpConsole Connection Error: Apro exception
What does this mean? What do I have to do to fix it? I made sure my Device ID was typed in correctly and that the TCPIP port was correct. If I can get this to work, I want to run Virtual Weather Station, WeatherLink, and Cumulus at the same time.
