Well for some reason when I open my GHL app on my iPhone and I am at home using WiFi I am no longer able to connect to my P4 in the app via WiFi. I can connect to it via the MyGHL connection in the app but not WiFi. The WiFi light on the P4 is green, but no dice connecting. It tries establishing connection but then shows connection failed. Connection to the device could not be established. Absolutely nothing has been changed setting wise at all. Just quit connecting. Any ideas why ?
