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:
