Roon server stops responding on Ubuntu 18.04 LTS

(David Green) #1

Core Machine (Operating system/System info/Roon build number)

Ubuntu 18.04 LTS / i5 Quad with 16GB Ram - Library on Synology NAS / Build number not known

Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)

Ethernet - Server & NAS on 1GB cable, controllers on Wifi.

Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)

2x B&W Z2, 1 Meridian 218, 1 MuSo

Description Of Issue

Roon server will periodically stop responding to the control app. Roon shows up as running using the HTOP command on Ubuntu, the server is fully accessible via the network (I use SSH as there’s no console). I have the roon control app on iPads. The Roon server periodically stops responding to the control app - just get the message “Waiting for Remote Core. Roon is still trying to connect, but it’s taking longer than normal…” Rebooting the server cures the issue, for a few hours or days, then it will randomly stop responding again.

Hi @David_Green,

Can you describe your network setup? What networking hardware is in use?

When one remote disconnects, are all remotes in this same state or do other remotes have the ability to connect?

The network setup is complex, but to answer the question:

When one remote disconnects, they all disconnect. It’s the Roon Server that doesn’t respond.

The cabled side of the network is managed by a Netgear GS724T switch. (Behind that is an FVS336v3G3 Firewall, but that isn’t part of the connection to the Roon Server).
Connected to the Switch are a number of TP-Link Wifi Access Points - due to the size of our property a single Wifi AP isn’t sufficient. The remotes connect via the Wifi Access Points.

Thanks for the info, @David_Green.

We have sometimes seen this type of behavior stem from the use of WiFi access points, as noted in our, Networking Guide. It’s hard to say if this is for sure the issue just yet, but I’d like to propose a test which should help us determine this.

If you have a Mac or Windows machine that you can connect via Ethernet to the network and you use this device as a remote, does this remote also disconnect from the Core?
