When I run VTscada afresh, the ports all are fine and data is read. However there are ports whose IPs are going through a VPN network. When I lose the internet connection and it comes back online later, VTscada only resumes local network IP reading, but not those going through VPN. Yet when I ping those IPs I can reach them. I can also reach them using other applications such as modbus tester. Why doesn't VTscada resume this connection. Also sometimes it loses the connection and never resumes. When I restart the application, all things resume normally.
