Describe the issue
I have a ROCK server on a NUC that has been working fine. I just unplugged it to move some equipment and when I restarted I could no longer connect to Roon. I am able to connect directly to the IP address and manage the server but not through the Roon app on Windows or my iPhone. I've double-checked my firewall and nothing has changed. I am sometimes able to log in to my Roon server, but it can't connect to Tidal or search, and it quickly flashes up to the screen that says "are you online". It seems like an authorization issue, but I cannot solve it.
Describe your network setup
I have fiber internet through Ezee Fiber to a self-managed network consisting of a PFSense Firewall and a Cisco Switch connected via Cat 5 cables. I have configured the PFSense firewall rules to enable communication with my personal devices on the LAN as well as with ARC. All has been working perfectly until Sunday when I unplugged the NUC to move it.
Move the contents of the /Cache folder to another location, such as your desktop.
Restart Roon Server via the Web UI and check if the issue still occurs.
From your description, it looks like your ROCK system starts properly, but the connection to Roon’s cloud services (login, TIDAL, search) is failing. Since the issue appeared right after you unplugged and moved your NUC, there might be a network configuration issue at play.
Could you please clarify a few details so we can narrow this down?
When you moved the NUC, did you reconnect it to the same switch port and cable, or to a different port/location in your network?
If you plug it back into the original spot where it was working before, does it start working again?
Is your PFSense firewall assigning the NUC a static IP address, or is it using DHCP?
Finally, please confirm whether other devices on the same network can access the internet and Roon services normally.
This will help us understand whether the issue is caused by a network routing or authorization change after the move.
Hi Vadim, thanks for your help and sorry for the delay. I tried the first solution and was not able to see my ROCK server folders remotely (I use a Windows computer). My next step will be to hook up a monitor and keyboard to work directly on the NUC, but I haven’t had time to try that yet.
To answer your other questions, I just moved the NUC from the top shelf to a middle shelf of a cabinet. All connections were the same as before. I am still able to see and use other Roon-ready devices on that network. I have the NUC assigned a fixed IP address through my PFSense DHCP server. As I said previously, I can connect to that IP address via the WebUI but it only sporadically connects through the Roon app. I’ve tried to connect via an iPhone and Windows computer with the same result.
We reviewed the diagnostic data from your ROCK and noticed the system date/time does not match the current date, which can break cloud authentication and cause intermittent behavior in the Roon app. Please check the following network items that commonly cause that symptom:
NTP / Time synchronization
From the diagnostics the clock looks wrong — ROCK may be unable to reach NTP servers.
Please verify on your pfSense that outbound UDP port 123 (NTP) is allowed for the ROCK’s IP and that there are no outbound rules or NAT redirects blocking NTP. When you have a monitor attached to the NUC, confirm the ROCK console’s date/time is correct.
Multicast / IGMP (device discovery)
Roon relies on multicast for Core/device discovery. On your pfSense and Cisco switch please check whether:
IGMP Snooping is enabled — if so, try temporarily disabling it.
Multicast filtering is enabled or traffic to 224.0.0.0/24 is blocked.
mDNS/Avahi reflection or multicast routing settings are interfering.
If multicast is filtered, the Core will appear only sporadically in remotes.
Brilliant! I had an error in my NTP settings for that VLAN, which must not have been an issue when I first set it up because I configured it from a different VLAN. Once I fixed that, everything worked again! Thanks so much for your help…I would never have found that on my own!
