Describe the issue
Roon lags like hell. Turning off background analysis, restarting devices, clearing cash is not working.
Thanks for writing in, it’s good to see you on the community again!
From a fresh Nucleus diagnostic report, we did see specific failures in reaching Tidals upstream servers, which could be improved from updating the DNS server on the machine.
We have seen users have a better experience in the past if they change their Router’s DNS servers from the ISP provided ones to Cloudflare DNS, Quad9 or Google DNS. Can you please give this a try and let me know if it helps?
Here’s a step-by-step on how to change the DNS settings on your Nucleus:
Open a web browser on a device connected to the same network as your Nucleus.
Enter the IP address of your Nucleus in the address bar.
If you don’t know the IP address:
Open the Roon app.
Go to Settings > Setup > Find Nucleus.
Note the IP address shown for the Nucleus.
Alternatively, use http://nucleus.local/ (on macOS or Windows with Bonjour installed).
Log into the Web Interface:
Once the web page loads, you’ll see the Nucleus web administration interface.
Change the DNS Settings:
Scroll down to the Networking section.
If the Nucleus is using DHCP:
Note that you cannot directly edit DNS settings under DHCP. You will need to switch to a static IP to specify custom DNS servers.
Switch to a Static IP:
Click on the Configure or Edit option under networking.
Enter the current network settings for your Nucleus (IP address, subnet mask, gateway) manually. These can often be found in your router’s settings or your current DHCP lease information.
Specify Custom DNS Servers:
Add DNS servers in the relevant fields. Common choices:
Google DNS: 8.8.8.8 and 8.8.4.4
Cloudflare DNS: 1.1.1.1 and 1.0.0.1
OpenDNS: 208.67.222.222 and 208.67.220.220
Save and Apply Changes:
Click Save or Apply to confirm your new settings.
Restart the Nucleus (make sure Roon Server is stopped) and let me know if you continue to experience the same behavior.
Hi! And thanks for help. By a mistake, I entered static IP of 192.168.0.348… (I know it shouldn’t be over 255).
Now, when I access roon application on my phone and I click “find roon os” it finds it right away with ip 192.168.0.248, but I cannot access it… not with my phone, not with computer. I restarted it many times (also the router) but it doesn’t help.
