Cant connect Rossmont waver controller

[acro_lover]

Hi everyone, i need help. I know that Rossmont are long gone but I have an old Rossmont controller with 2 pumps. I downloaded old apk file for the Rossmont "In touch" app. Then i connected the app to the Rossmont network and when i try to connect the app to the controller is says: "Incorrect serial number detected. Reset and retry". I reset it multiple time, but still doesn`t want to connect. Sometimes is says: " Are you sure that the device is connected to the Rossmont network. Reset and retry." Anyone knows how to make it work?

I’m wondering if the app service is shutdown now. I personally have never heard of rossmonts before
