Roon Server is an application that runs in the background on Windows - it does not have a user interface of its own.
You change settings by using the main Roon application. Go to Roon’s > Roon ARC screen to access the ARC settings. Can you post a screenshot of that screen?
You are so kind for helping me. I’ll work on the screenshot in a minute. My class just walked in the door. I am a high school science teacher in North Carolina…
I am about to give up on the ARC App. I’ve gone into the Spectrum router settings and activated UpnP (sp?) protocol but still get the same “cannot connect” message.
I’m sorry to hear that you’ve hit a snag, if you require help from the support team, please open a support request in the Support category of the forum and fill out the issue report template with as much detail as possible. That will help Tech Support get you up and running again.
Please include the error message that the Roon ARC setting displays.
