Having a rather strange problem where my iOS device seems to disconnect from Roon, and thereby start a reconnection process that disrupts the user experience significantly. It feels like the app has crashed in some cases.
a) Doesn’t happen as much or as noticeably when the server moves to Linux or MacOS (currently it’s on Windows Server 2016). I’ve turned off AV and Firewalls on the Windows box with no difference.
b) Other connected devices behave (eg Nexus tablet is fine).
Roon Server version: 1.5 (Build 323).
Operating system: Windows Server 2016 Standard - 64bit
Hardware: Intel NUC NUC7i7BNH
iOS: v 11.3.1 on iPhone X, running Roon Version 1.5 (323) 64bit
Music is stored on SSD in NUC (2nd drive, internal).
Approximate size of library: 5000 songs
I have tried power cycling - no change.
The reproducible case is simple: Start iOS Roon app. Make sure that Keep Display Alive is set. Browse to Song, play. Browse to other song, View Lyrics. Wait - in about 2m or so, the connection drops, and the context of the Roon iOS is lost and goes back to (usually) the last known state.
Wifi for iOS is via Google Wifi. All other devices are connected via Ethernet.
Problem as described above does not occur on Roon via Nexus tablet.
Problem either does not occur or is less disruptive when server is moved from Windows to Linux (or MacOS).
Almost seems that the Windows server drops the connection or refuses to reconnect?
I see the following roughly when the issue occurs:
I’m guessing that maybe there are differences in TCP/IP settings between Linux/MacOS and Windows Server 2016 Standard vs older versions of Windows that may affect how connection between client and server are handled?
Do you have any type of battery saving settings turned on on the iOS device?
I think the next step here is to enable some diagnostics on your account so our technical staff can get some more insight into what’s going on here.
However, before I enable this feature, I’d like to ask for your help ensuring we gather the right information.
First, can you please reproduce the issue once more and note the time at which the error occurs. Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.

Does this only happen with the iOS Roon app? Are you able to still access Roon using other remotes during this time? ** I have only used my iPhone, and occasionally my iPad, to access Roon.
Do you have any battery saving features enabled on your iPhone? ** which battery save feature are you referring to?
Are you still able to access the network on the iPhone when this happens? ** Yes, the rest of the network was fine
Does this happen when you are using the remote app or only after it’s been idle for some time? ** This happens when I am using the remote app, approx after 15 to 20 minutes of play
For your guide, my Roon is connect to an Ayre QB8 DA converter, and Seagate external HDD. Thanks
Now that I have the timestamps, diagnostics have been enabled on your account. The next time your Core is active a diagnostics report will automatically be generated and uploaded directly to our servers
Once that’s been received, I’ll be sure to update this thread and pass the diagnostics over to the team for further analysis. I’ll also be sure to include the info that you sent in the PM.
May I ask that you confirm the name of the iOS device that was used during the test for the timestamp you shared, as well as the name of the Roon Core machine? This way I can ensure that the tech team is referencing the diagnostics report for the correct devices.
Does this happen for both devices, or only the iPhone?
Do you have Low Power Mode enabled?
Just to clarify, you are actively using the remote and it is not just sitting idle? Is there anything specific you are doing on the device when this happens? Changing tracks, clicking thumbs up/down in radio, etc.
May I also ask that you describe your network setup? Can you give me details on your Core device? Is you Core connected via WiFi or Ethernet? What kind of networking hardware are you utilizing?
