Describe the issue

Out of sudden, one of int amp lost commection only with Roon(NAD C399. Only Roon connection is gone. I still can use machine with BluOS or Tidal Connect)) and only my Iphone doesnot connect to Roon. (Means my other Roon Remote decices are fine such as Ipad, Macbook and Windows Surface)

Funny thing with my iphone is that I cannot conmect to Roon with Roon remote app but I still can connect to Roon with Roon Arc app.

Hi @Donghyun_Kim,
Thanks for writing in to ask us about this issue.

This is an important point. It tells us that the interference is happening with your Roon server’s access to your local network. For testing purposes can you try connecting the Roon server directly to you router and see if the connection with your iPhone is more stable?

Another thing I noticed in your account information is that we have multiple local IP addresses shown for your iPhone. Some are in the same subnet as your other devices while some aren’t. Can you try changing your router settings to use an IP range that is all within the same subnet?

Hey Daniel,

  1. My Roon Core is directly connected to the router with wired connection.

  2. Let me try subnet co figuration change. Let me know how to.
    Thanks.
