“Nucleus (Roon OS1.0 (build 227), Version 2.0 (build 1143) production”
Connected to router via direct ethernet cable, using Roon Remote App on iPhone and MAC, audio devices: Sonos and Cambridge CXNV2 streamer.
Issue: Nucleus/roon remotes have been running fine for the past 1.5 years. Yesterday I had to re boot my internet (which I often do) and the Nucleus has lost connection with the remote apps. I can see from the administration website that my Nucleus seems to be operating with no issues. I can also see all my files etc. when I connect it to my MAC ( flashing green and solid amber lights on the Nucleus).
Having attempted numerous re-boots on both my internet router and the Nucleus itself without succes I’m getting the “Choose your Roon Core” screen on my remote apps. They are seeing my Nucleus but I’m just getting an “initializing” message (and the “Connect” button is a dark blue and won’t respond).
My internet is working fine, apps and software are all up to date. I have tried deleting the apps and re-installing them. Nothing seems to fix the problem.
Double check the IP addresses of the Nucleus and your other network devices. You can use a program link Fing. If the Nucleus, for example, had a fixed IP address, the network reboot may have changed the base network subnet.
For Roon, all devices, need to be on the same first three numbers of the IP address. aaa.bbb.ccc. x.
Another thing to check is that, you should be able to get to the nucleus web ui from a web browser on the Mac.
No, that’s the problem. Despite the Nucleus seemingly being online with no issues (as per the administration systems report)…my Remotes(i.e MAC and iPhone) won’t connect to it…its perpetually “initializing”,
I carried out these steps precisely but it didn’t have any effect. The monitor displayed the details of the Nucleus and the message: "Roon can be accessed by OS devices on your network. If you don’t see this device there, check “Roon OS devices on your network”.
It also displayed the IP address of the Nucleus.
When I typed in “resetnetwork” nothing happened. I rebooted the nucleus and attempted this several times with no success…
Yes, it all looks ok on Admin page…and the Nucleus is certainly connected to my network… think I mentioned above that I’ve also tried re-installing my Remote Apps…I even plugged my MAC directly into my router…still stuck on “initialzing”…
For your iOS device, when it cannot find the server, the screen has a blue help button which opens a screen to allow you to enter the server’s IP address. Instead use 255.255.255.255 and see if that enables that device to connect.
This is indeed an odd issue. I’m seeing your Nucleus online and reporting to us but I am seeing an error in diagnostics that seems to show the Nucleus is having issues with communications on your intranet.
11/10 17:50:21 Debug: [tcptunnel2] error in go_local_to_remote: Unable to read data from the transport connection: Operation canceled.
This might indicate something is stopping the communications as, @Rugby suggested. Can you try his suggestion and report back?
Also, I would like to bring this up with my development group to get some more options here. Can you power on your iMac and leave it going so I can get diagnostics from it as well? I’d like to see what the iMac sees as happening and this will be instrumental in getting a complete picture.
