Description Of Issue
I have started experiencing an intermittent but regular occurrence of Roon Remote (on both iOS and macOS) and Roon Bridge (on RoPieee) losing connectivity to the core. I suspect that this started occurring as I upgraded the core OS to Ubuntu 20.04.1 LTS but it may be coincidence, prior to the OS upgrade Roon had been extremely stable for many months. The remote app will stop responding and at the same time the music will stop playing. To get the music to start playing I have to wait for a reconnect of the remote app and press play again (this normally reconnects without intervention within a few seconds). I retain connectivity to the core using other methods, for example I can have a remote ssh session and can actively watch a ‘tail’ of the log files (although I can’t decipher them) while the connectivity is lost within the Roon system. The last occurrence of this was at 21:09 – 21:10 PST on Nov 30th (today) and this might happen about 3 or 4 times in an evening. This happens both when playing locally stored FLAC files or streaming from Qobuz.
Troubleshooting Performed So Far
Everything has been rebooted.
Checked that all devices are fully patched and up to date.
Disabled services (like Tidal) and storage devices have now been removed.
