I have a 6600; it works fine with PC on LAN. In the past, I have been able to connect my laptop to it remotely and use it OK. Since version v2.3.9, I have not been able to connect the laptop. It seems to see that there is a rig there (shows the rig and my callsign), but when I hit Connect, it hangs for a while and then gives the modal error box "Unable to connect to radio. Please try again". I have the iOS version of SDR on my iPhone, it can't connect either. I have tried reloading the default profile from local system. The desktop (which works), radio, and laptop are all running v2.3.9. What is wrong? Does the new version need me to open a port on my router that is not open currently? Or?
