I can’t connect to my nucleus, since I tried a reboot.
My router/modem is a tp-link archer VR600 and a tp-link AC2600 range extender
Hi @stephen_ollerton,
Thank you for reaching out to us about this issue. Can you give some more details about what’s going on? Can you tell us what you see when you try to connect?
I noticed that you have a second server that has been used recently. Was this server active when you tried to connect to the Nucleus? If it was then you will need to deauthorize the other server in order to use your Nucleus.
Hi Daniel
I tried a reboot days ago and it did it in about 2 seconds.since then the Nucleus isn’t showing up when you choose the core only this MacBook Pro.
Can you explain a bit more about how your Nucleus is set up within your network versus your Mac? Let’s bypass any range extenders for now, and make sure you have a direct connection from your primary router to your Nucleus via ethernet.
Please make sure that Roon Server is stopped on your Mac - you can do this via the taskbar on your Mac.
We’re still not able to connect to your Nucleus from our servers, could you please use the directions found here and send over a set of Roon Server logs from the Nucleus to our File Uploader?
Thanks!

Is the Nucleus connected directly to your router? If not, please get a direct ethernet connection directly to your router as a next step.
With that, can you also access the webUI and share a screenshot of what you see? Here’s more info on that:
We’ll be on standby for your reply, thank you! 
Everyone
The Nucleus is directly connected via Ethernet cable to the router ,Laptop disconnected from Roon .
Someone has mentioned corrupt operating system or currupt hard drive that it could be.
The Nucleus has changed its IP address, it can’t find itself.
Hello @stephen_ollerton ,
Your Nucleus isn’t showing up at all as being online recently. Is it still turning on properly? If you try to plug in an HDMI cable from the Nucleus to a TV or monitor and have it turned on, do you see any output? If you have no output, please reach out to the RMA team using the below link:
