Describe the issue

Unable to access Roon Rock
Until now, I am running Roon on a NUC 7i7BNH, Win10, ip: 172.17.10.
I decided to switch to ROCK – installation on a second NUC (same specs)
Installation was o.k./successful … but the configuration screen did not appear. Instead, I got the message that Rock can be accessed on any web browser at 172.17.65.208.
…but I can’t access this site in either way (= this site is not available)
When looking at my other NUC (Roon on Windows 10, ip: 172.17.10.) and going to setup, Rock is found on 172.17.65.208
[network: Unifi router, Unifi switches…. ]
What am I doing wrong? Which steps do I have to follow in order to switch from Roon/Windows to ROCK.

Describe your network setup

Hi @Udo_Eimermacher,
Thanks for writing in to ask us about this. I activated diagnostics on your account and took a look at your ROCK’s logs. Everything seems to be running properly. Are you able to connect to the ROCK from an app?

What happened when you went to that IP address?

What is your Netmask set to? If the netmask is set to 255.255.0.0 (which is perfectly valid for ip address ranges in the 172.16.0.0 to 172.31.255.255 range), then all of the ip addresses that you quote are valid and on the same subnet.

If, however, your subnet mask is set to 255.255.255.0, then you have two different subnets.

Have you tried opening a web browser and going to http://172.17.65.208 (You should be able to follow that link)?

You should be able to find out what your netmask is set to (and it should be the same on all devices if using DHCP to allocate ip addresses) by looking at your router LAN settings.

If you can’t find the subnet mask on your router, you can find it on a windows machine either from the ipv4 properties of your network connection properties or, more easily, from the command line terminal using the ‘ipconfig’ command:

e.g. On my Windows Computer, my subnet mask is set to 255.255.255.0 so I see:

C:\Users\wade>ipconfig

Windows IP Configuration

Ethernet adapter Ethernet:

   Connection-specific DNS Suffix  . : hagrid
   IPv6 Address. . . . . . . . . . . : 2a00:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
   Temporary IPv6 Address. . . . . . : 2a00:yyyy:yyyy:yyyy:yyyy:yyyy:yyyy:yyyy
   Link-local IPv6 Address . . . . . : fe80::7cb9:cb7b:9474:9edb%5
   IPv4 Address. . . . . . . . . . . : 10.212.153.150
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : fe80::ce28:aaff:fe2a:340%5
                                       10.212.153.1

This is normal. There is no ‘configuration screen’ on the monitor to which a NUC is installed when RoonOS (as installed by ROCK) is running. Only a small amount of information text including, as you have seen, the ip address.

This confirms that ROCK installation is up and running and is on the network at the 172.17.165.208 ip address.

If you run a Roon Client, can it see the Rock installation?

You will have to logout or disconnect from your existing Roon Server:

And then connect to the ROCK Roon Server when offered a choice:

If you only ‘disconnected’ from the old server, then you will have to ‘unauthorize’ the old Roon Server:

Then you can log into the new server.

Hi Daniel,

I can’t access 172.17.65.208 (not with a browser nor with a Roon client.
Trying to access this address, I get the message that the site is not available.
Regards,
Udo Eimermacher

Hi Wade,
Thanks for your detailed description - I will check the net mask settings and follow the steps you described tomorrow… keep you posted>.
Kind regards,
Udo

First check: netmask is 255.255.0.0 (but cannot open/ access 172.17.65.208).
Next update tomorrow.
Udo

Hey @Udo_Eimermacher,

Keep us posted on how reviewing the net mask goes. It may be easier to temporarily setup a direct hardwire ethernet connection to your primary router using your new ROCK and other remote devices to test if your unifi switches may be causing you issues.

Let us know! :raised_hands:

Hi again,
Although the netmask settings are OK and the NUC-2 appears to be correctly installed with ROCK, and despite following all the steps as Wade showed them, I never get the option to choose Rock as the new server. I only get the option to log back in to the old server or one of the other Windows remotes… even when logged out and disconnected.
Desperate now and back on the Roon Windows configuration.

Hey @Udo_Eimermacher,

When you review your device list from your router settings, are you able to see the NUC?

Lets first ensure that the device can be found on your network.

Is this the case no matter the remote device you’re using?

11

Hi Daniel, yes the Nuc is visible. It is practically not feasible to connect directly to the router (the location is 2 floors down and only serves as a place where all utilities are installed)

13

Yes, no matter the remote I’m using

14

Today ROCK appeared for the first time on the selection screen…unfortunately I did not get the option to connect (see attached print screen).
What exactly happened: I disconnected the current Roon server, but by mistake I had not yet started the NUC with ROCK. When the Rock had just started, the selection menu appeared, but it was not possible to actually make a connection. After about 1 minute, the choice disappeared again.
Conclusion: if ROCK is on/started, the selection menu does not appear… if Rock still has to start up, the menu does appear, but I cannot connect… and after a minute the choice disappears again. Any idea how to find a solution?

That screenshot says that the Roon Server on the ROCK system is build 1234 - which is an old version.

You should first go the the Web Administration Interface of the ROCK and reinstall the Roon Operating System - this will install the latest build of Roon Server as well. This is stated in step 6 of the ROCK Install Guide:

Be sure to also confirm that ROCK is on the latest version. You can trigger ROCK to update by selecting Reinstall from the Web UI.

16

Hi,
Thanks for your help - how to access the Web Administration Interface? Or where can I download the latest version of ROCK?
I downloaded the file “roonbox-linuxx64-nuc4-usb-factoryreset.img.gz” from here : https://help.roonlabs.com/portal/en/kb/articles/roonos-recovery… (this is indeed the 1234 build)

17

The ROCK installer is not updated very often and does not usually install the latest version of Roon Server.

After installation, run the Web UI and then click on the ‘Reinstall’ button as @Geoff_Coupe stated above. This will automatically download the latest version of RoonOS applicable to your NUC and the latest version of Roon Server software and install them.

On new ROCK installations, the WebUI can be accessed using http://rock or, if this doesn’t work, http://<Rock_ip_address>

18

Hi Wade,
We are back where the discussion started: I can’t access the web UI, and so I cannot click the Reinstall button. http://rock and http://<Rock_ip_address> does not provide
access.
Wouldn’t it be much easier and user-friendly to update the Rock version and make it accessible as easy as the Windows and Mac downloads?

19

Sorry, I though you had fixed that issue. IMHO, there is no point in going any further and trying to connect a Roon Client until the Web UI issue is resolved.

20

Then we need to get to the root of your network issue first. You’ve said that you can’t connect your NUC to the router directly. Why not? Being two floors down and in a room where all utilities are installed shouldn’t be an issue? Or is your network in an apartment building and it is being shared with others?

Do you have a reason for using a 255.255.0.0. netmask? In particular do you have more than 250 odd devices connected to your network?

If not, you could try setting the netmask on your router to 255.255.255.0 (which is much more conventional for home networks). After you do this you will have to reboot (or otherwise release and re-obtain DHCP leases) on all of your network connected devices.

What happens if you run a command terminal on your windows machine and type “ping rock”?

What happens if, in the same terminal you type “ping 172.17.65.208”?

Do you have any firewalls installed your computers (other than the one in the router)?
