After a reconfiguration of my LAN I can’t reconnect my Roon to my Unifi NAS in order to keep my automated backups up to date.
Roon Nucleus ONE is on 192.168.7.12
Unifi Router is on 192.168.5.1
Unifi NAS is on 192.168.4.3
All three devices are communicating with each other in other respects fine.
The first screenshot shows the Roon Backup page on top of the Unifi NAS page showing the folder path where I want the backup to go, and the second shows that the smb://192.168.4.3 is (hopefully) correct.
In the Roon NAS Troubleshooting Guide it suggests removing any special characters from username passwords, but the Unifi NAS UI won’t let me do that - there are a couple of “@” & “!” in the password that I can’t delete.
I am not familiar with Unifi devices.
But one thing intrigues me: what network mask do you use on each device?
Can you ping your NAS server from the Roon server?
Everything on my network uses 255.255.255.0 - if that is what you are meaning?
My networking skills are not good enough to know how to ping from the Roon Nucleus ONE to the NAS I am afraid, but I can play music that is stored on my NAS through a Roon endpoint through the Roon controller, so I am confident that there is no firewall / network reason to prevent the Nucleus ONE & NAS from talking to each other.
Yes, the Nucleus will read the music files on the NAS. The two communicate well.
From your Mac, you can connect to the address from your file manager smb://192.168.4.3/jjb/Roon/Backups/RoonBackupsNew?
Does the folder (RoonBackupsNew) exist and is it shared with the correct permissions (read and write) for the user jjb?
Are the music library files stored on the same share (smb://192.168.4.3/jjb)? Are you using a different account to connect to it?
In order not to complicate things with my admin user and password (which to be honest I didn’t really want to “share” with the Roon software , I have created another “root” folder on the NAS called Roon, and created a sub folder called Auto_Backups ; I put a temporary textedit file inside called 20251114test. I created a new User with its own username called roon & a new password.
When I type smb://192.168.4.3/Roon/Auto_Backups in to a browser it now opens up a browser window and shows the textedit file after prompting me for the username & password. All good so far.
But if I put the same smb://192.168.4.3/Roon/Auto_Backups in to the Roon backup Network Share Location, along with the correct username & password, it comes back with an Unexpected Error error.
So … the NAS can see the folder, the MacBook can see the folder within Finder, Roon can see the NAS too play stored music, but it doesn’t want to put a backup on a network share …
Good evening,
Sharing is working. That’s already a good thing.
I’m confused as to why music folder sharing is working but backup sharing isn’t.
For your information, I created an account called “roon” on my NAS server with a password containing the special character ‘@’ and I was able to connect to a shared folder on my NAS from Roon.
Can you send me a screenshot of the SMB protocol settings for the NAS server? Is there such a thing as smbv1, smbv2, smbv3?
Hello,
UNC links of the type \\server\shared_folder are used in Microsoft Windows environments only, to my knowledge. In Unix environments and their derivatives such as Linux, FreeBSD (MacOS), etc., UNC links smb://server/shared_folder are used.
For me, the NUCLEUS ONE server runs on Linux, so the UNC path must be smb://server/shared_folder.
If the Roon server had been installed on a Microsoft Windows environment, the UNC path would have been “\\server\share_folder”.
According to your original post - you are using multiple (3) subnets to segregate your network. Have you built out your firewall rules to accommodate this? Roon uses certain discovery protocols to find devices on your network. You may also need to look at mdns discovery across the subnets.
I am 98% this isn’t a firewall issue, yes. At present, all firewall rules are set to “Allow All”, and all ports are also set to allow all. I am at the early stages of implementing the VLANs, so have yet to start splitting things out.
This is the Admins & Users page of the NAS control Panel, with some details redacted. It shows the Roon user that I created for the Roon automated backups
Can you increase the permissions (from editor to administrator) for testing purposes?
Regarding sharing the music library, you need more rights. That’s all I can think of!
To follow up on what @MikeD said. Your network is more complicated than normal for a home network, probably due to your Unifi router.
You should simplify it if you can!
Sorry for the delayed response but I have been very busy over the weekend doing a ground up re-build of my network trying to make it simpler. I now only have two VLANs - one for “infrastructure” and computers etc, and the other for IoT etc, but it is far simpler than it was. But with over 175 items connected to the router it has been quite a task …
Anyway, the good news is that even with the Roon Nucleus ONE on the IoT VLAN and my NAS on the other VLAN I have been able to automate Roon backups which is great news! Problem SOLVED!
Still not 100% sure how, but it was probably a mixture of several issues all ganging up to cause a block that a simpler regime has made possible.
So thank you all - especially @Cyril_VARENNE - for your help & patience, it has been most appreciated
