Scanning HDHomerun not working

[dschlic1]

I am new to Argus TV, having just installed V2.3. The recorder console is finding my HDHomerun and is setting it up properly. I have set the timers to 20 seconds. However I try to scan for services, none are found. The Recorder console is showing good signal strength and also good signal quality. I can also use the HDHomerun view app to watch TV with no issues. Its almost as if my system is missing a decoder. Can someone weigh in on this and help me out?
