Description of Issue
I’m having a real issue with my Nucleus+ Core losing connection with my network.
When the Core does down, none can access. Occasionally I’m unable use my Mac browser to access the Nucleus+ so I’ve lost connection completely. This happening intermittently every day and multiple times a day.
I was wondering if I should reinstall my Nucleus+ software but I get a warning that doing so will be destructive. I am also unable to get a current backup. Probably due to the intermittent drops.
Can you post a screenshot of your Nucleus Plus’ web administration page? I am wondering if your RoonOS database drive may be full with such a large library.
That’s interesting. Your Nucleus Plus has been operating for almost 5 hours but the Roon server application seems to have rebooted in that timeframe and has been running less than 90 minutes. Your database storage looks fine.
Have you restarted your Nucleus Plus manually in the past 90 minutes?
A couple of observations from looking at diagnostics. I am seeing connection failures in the logging that indicate connection issues in general and this lines up with what you’re seeing. One of the failures is connecting to Cloudfare DNS (1.1.1.1).
Some ideas.
Do try reinstalling from your Nucleus WebUI. It doesn’t affect databases. There is a chance something could go wrong but I don’t see the situation being any worse than it already is.
Try changing your DNS to Google instead. 8.8.8.8 and 8.8.4.4
Can you please explain your modem and router setup (make/model for both)?
Typically you can change these in your router also. I did that due to DNS problems with my ISP, and it solved every connection issue in my home immediately.
These would be changes to your router. We might be able to get you a guide or general sense of direction in doing so if you provide us with your modem and router make/model.
Can you please supply the make/model of the Spectrum modem? I’m thinking this is a modem/router combo and if that’s the case, there might be multiple subnets in use and two devices doing routing. A likely cause of your issues if this is the case.
@Wes, the modem appears to be a Hitron EN2251 DOCSIS 3.1 modem with a 2-port eMTA for SIP voice services. I am not sure if the eMTA would interfere with data routing and act in some way as a gateway/router. There is no WiFi on the EN2251 from what I can see in the specifications.
Given the age of the Apple router, that may be a factor here also.
I didn’t have any issues with Roon until the 2.0 update came out. I reinstalled the nucleus operating software and restarted Roon server. It worked for several hours. Then when I tried to force a backup it locked up again. I believe it has something to do with the backup. Would that make sense?
It may very well have something to do with it. Let’s try this then. Please ensure you get a new backup and when done, try things out testing everything thoroughly before attempting to reimport a potential would-be problem. Please let me know how it goes. If this indeed proves a database issue is at play we have few options but we’ll try everything we can.
