Constant Core Disconnecting and Reconnecting a Split Second Later

Running Roon Rock on an Intel NUC8I7BEK i7 8559U 8GB RAM 250GB SSD with latest firmware

I have it hardwired via Ethernet to an Asus RT-AX88u Pro and stream to various BlueSound Nodes and control via my iPhone and Macbook. I stream Qobuz and have a large local storage of music (About 6000 albums) that is on two separate hard drives attached via USB to the Intel Nuc.

I have used this setup for a while with zero issue.

Today the Core kept disconnecting and then literally a split second later reconnecting. It would boot me out of whatever I was doing. It does this repeatedly and constantly. I double checked the hardwired ethernet connection on both ends and I tried all of the following with only worsening of the problem:

  1. Rebooting the Core
  2. Rebooting the remote apps
  3. Rebooting the Router
  4. Restarting Roon Server Software
  5. Reinstalling Roon Operating System
  6. Resetting Roon Databse and settings

None of these problems have solved the issue. If anything its worse. It disconnects and reconnects so frequently that I literally cannot select my backup to restore my Roon Core after resetting the database and settings as it boots me out of the settings section every time I disconnect and reconnect. This happens about every 5 seconds.

Please Help!

Can you check if you have any package loss when you try to ping the core from the Mac?

Just in case you are not familiar

  1. Open Terminal on Mac
  2. Enter the command “ping -c 60 aaa.bbb.ccc.ddd”, replacing aaa.bbb.ccc.ddd with the ip address of you core.

This will ping your core 60 times (approximately 1 minute) and will provide a summary of the results
Check to see if you have any package loss.

Same on my Roon rock running on Proxmox. Since last update i get disconnects and a high CPU usage on Roon Rock

Edit: Last night cpu usage was around 25% on a 4 core VM, without using Roon. Normaly its arround 2% when idle

60 packets transmitted, 60 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 2.936/18.523/774.765/98.485 ms

Looks like no package loss

No package loss, but those are results that do suggest something is up with the network. 774ms max is awfully slow in a LAN. Even min value of nearly 3ms could be considered fairly slow.

For comparison, this is what I am getting:

60 packets transmitted, 60 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.177/0.421/1.432/0.200 ms

Do you have any other devices on the network for which you can do a similar ping? Just trying to isolate if the problem with with the NUC or the network on general.

Edit:
Even a ping to Google’s DNS only gets met to 7ms:

--- 8.8.8.8 ping statistics ---
60 packets transmitted, 60 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 5.826/6.481/7.009/0.317 ms

I agree, there’s something amiss in the network with those ping responses. Even a ping via wifi should average 4-7 ms.

This is the result with me pinging my Roku

60 packets transmitted, 60 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 3.971/20.959/140.088/35.319 ms

This indicates its the network?

It doesn’t make sense that its the network. I have changed nothing and the rest of my network/devices work fine. It is literally only the Roon Core that is having trouble. I can stream directly to my nodes with Qobuz with zero issue

Does indeed seem to suggest something is off with the network.

You mentioned that the core is hardwired. Is the same true for other devices such as the MacBook and the Roku? Or are they on WiFi?
WiFi can be very sensitive and suffer from interference from a lot of sources that are not necessarily related to your network.

Also, do you have just the one router or are there any other network devices in play? Think switches, access points, power lines…

Macbook is wireless. Roku is hardwired. I have a switch for some extra ethernet connections but the Intel Nuc is directly hardwired to the Router. No other access points or routers. I just tested pinging my Core from the Asus settings page instead of the Mac Terminal and got the results below:

60 packets transmitted, 60 packets received, 0% packet loss
round-trip min/avg/max = 0.282/0.685/0.981 ms

compared to a Mac terminal ping results just after

60 packets transmitted, 60 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 2.819/9.836/105.443/18.566 ms

Good idea to ping the core from the router. That looks a lot better.
From this, I would focus on your WiFi being the source of the problem.

Options to explore:

  • What are the ping times from the Mac when bringing it closer to the Asus router? If these improve, how does Roon handle from there?
  • Most routers/access points offer the ability to switch channels. This can help when you get interference on a specific channel. Some routers offer the possibility of automatically switching channels.

Macbook sitting directly next to router

60 packets transmitted, 60 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 2.448/7.448/120.300/17.734 ms

Router already set to auto for wifi channels.

Maybe it is the Wifi but honestly nothing in my network has changed and Im still getting the full 800mbps download speed over WiFi that I pay for with my ISP

Even though there are still some fairly long round trip times, the average value in the ping times of your last two results is substantially better than what you had initially. Going from more than 18.5 down to 9.8ms and even 7.5ms in that last these is a significant difference.

Have you retried opening Roon on the Mac? Is it still having issues connecting to the core at this time?

Yes tried reopening Roon on Mac with it right next to Router and have the same issues

If I’m not mistaken, ROCK also has a webpage to which you can navigate from the browser? Are you able to navigate to that page?

Can still access the web page via IP address and update/reload settings without issue. I can still connect to my hard drives connected to the intel Nuc over the network without issue but whenever I try and connect to the core via the app whether it’s my phone or computer it just isn’t working

Is the core on the same build als your Mac and phone?
Latest build is 1303, released yesterday.
There are a few topics on the community from users who are having issues with updating and connecting to their core.

It is build 1303

@Support Can you please weigh in? Thanks!
