I have an OpenSpot 4 Pro connected to wifi and able to be connected to through the web interface, but when I try to connect to the openspot through the app it get a communication error. The status led is green and looks like it is running normally but the error says to make sure it is connected to the internet, even though it is on the same wifi as the phone I am trying to copnnect with. The error message mentions a fallback address, is that something that I will need to set or is it something else?
