I have an RT-700 grill and really like the WiFi feature that connects to an app on an iPhone! The issue I have is that my internet filter blocks some traffic which is required to load the app and list my grill. I have to disable my filter before I load the app and then after it is loaded, I can enable my internet filter again and everything works fine. What do I need to unblock in my filter to allow this traffic? Is there a URL or an IP address?
