If you are still able to access the homepage, that ‘Network Error’ message isn’t a big concern — the app sets a specific timeout so if it didn’t get back the controller data within the timeout it displays Network Error. When you have a large number of programs or a large number of zones, the controller data may take a couple of seconds to send, triggering this timeout, but the browser’s built-in timeout is usually much larger, so if you can still access the homepage you can ignore that message. I have communicated with Samer to suitably increase the timeout on the app side.
