Whilst using Roon app on iPad or iPhone the Nucleus server stops and I have to wait for about 4-5 minutes before bring able to listen again. Sometimes rebooting the app helps but not always. Seems that the Nucleus loses the network connection.
Hi @Manfred_Blanz,
Thank you for your post.
Diagnostics indicate that your remotes might be connecting to a separate subnetwork than your Nucleus - if you haven’t intentionally separated VLANs on this network, then I’d double-check that your router or another piece of network hardware isn’t inadvertently creating this second subnetwork.
In any iOS devices, try settings a Fixed (not a Rotating) Private WiFi Address in your WiFi settings.
Can you please share a screenshot of the RoonOS Web administration page for this Nucleus? This should contain information about the network interface and also give an indication if there’s any background crashing.
Hi Connor,
Sorry my late reply. Please find a screenshot of the admin page attached. In between I switched off the IP6 functionality which seems to make it a bit more stable.
The nucleus is directly connected to the router via Audioquest cable.
The router is a Fritz!Box 7590, DSL250 Mbit connected.
I need to mention that there is a Wireguard VPN to my company network installed which maybe could cause a problem. If needed I can send a screenshot of the config.
Hello @Manfred_Blanz ,
Thanks for those details. A VPN can certainly cause some issues. I enabled diagnostics for the Nucleus and I did notice something interesting here, which is that it appears that RoonServer is crashing during a backup at times. Are you noticing the same pattern on your end? Can you try to perform an OS reinstall from the WebUI to see if this helps?
Hi, I saw this issue a few weeks ago and installed a new backup source last week. Just re- installed the software let’s see if it works stable now. Maybe you can check from your side if there are still any issues.
Hi @Manfred_Blanz,
We’ve pulled an additional set of diagnostic logs from the Nucleus post-backup to be sure.
There aren’t any obvious issue, although ICY server URL addresses (internet radio) aren’t always resolving reliably.
You can try changing the DNS server in the Fritz!Box router to Cloudflare (1.1.1.1) or QuadNine (9.9.9.9) or another reliable server, if the ISP defaults are assigned.
Please reach out here if you encounter any dropouts. This thread will remain open for a few more days, just in case.
Hi Connor,
Sounds good for the moment. I have changed the DNS server as proposed and we will see how it is going on.
Thx for your kind support!
Hi @Manfred_Blanz,
Great, we’ll look forward to hearing the results of the DNS switch!
