Description of Issue
ARC is properly connected to the Nucleus+ as I see the blue check and the port number
I can see ARC in CarPlay when in my car
I can play anything without problem that I have downloaded
I have not been able to stream anything. I get poor connection errors or the loading symbol/text stays on screen.
I have tried all the different streaming settings in ARC and still no luck
Could it be that there is some problem with port forwarding that is preventing streaming from my Nucleus + server to ARC via CarPlay? I thought if there is a blue check in the ARC set up panel that means it is all set up but maybe not?
Thank you for your patience as we worked through the queue to investigate your report. We have a few questions to illuminate some networking details that should expedite our ability to resolve this issue:
Is your Nucleus+ hardwired to the router or an access point? According to ARC diagnostics, the app can reach your Core but then receives time-outs immediately. If you’re receiving poor connection errors with streaming content on the road - even with solid 5G coverage - then we’ll want to investigate the upstream connection on the network.
For due diligence, are you having any difficulty with streaming content (Tidal/Qobuz) in Roon Remote on your home network? Are you having any difficulty connecting with your remotes, or playing to any endpoints?
Please refresh the port test in Roon → Settings → ARC several times to see if it gives a failure diagnostic. If so, please share a screenshot here.
Roon logs from your Core show network dropouts and request failures to Roon’s servers, further suggesting the issue might be a Core/local network snag. Do you have any VPNs or other network security engaged, or multiple subnets?
We’ll follow up promptly once we receive your reply, and do our best to restore reliable playback in ARC as soon as possible.
My Nuclues+ is hardwired to a switch which is hardwired to my router.
I have no problems streaming Tidal via the Roon app on my home network.
Not sure what you mean by the “port test” but from ROON/Settings/ARC I reset the port several times and no problem. Let me know if I should try something else in this regard.
I do not have multiple subnets but there might be something there. My wife might have set up a Norton VPN on her PC which is on the same LAN as the Nucleus+. I am the only one trying to use ARC from my car and I do not have any VPNs set on my devices. My wife is out of town at the moment but I have a question in to her about what exactly she did with VPN. I could access my router’s logs but, in the past I have not had much luck interpreting the entries there.
I was wondering if somehow the port forwarding is not set up correctly. I went into my Fios router and did not see any obvious port forwarding rule for ROON but I am assuming that the blue checkmark in the ROON settings ARC page indicates that it should not be the problem.
PS. I just did a hard reboot on the router as I understand that is the only way to update the firmware on FIOS Quantum routers. After that I tested ARC sitting in my car in the garage. Still no luck. Loading……….for ever.
Diagnostic reports from ARC again confirm repeating failures to reach the Core despite properly autoconfigured port forwarding via UPnP. In some cases, a device is refusing the connection. Having reviewed this thread, we’re suspicious that either the VPN you mentioned or the network switch is filtering the Roon Core’s connection. These errors aren’t limited to ARC - going back several weeks, the Nucleus+ struggles to reach Roon’s own servers in logs.
Is this a managed switch? If so, what model? I recommend testing with Norton VPN disabled on your network if possible, just to be sure.
Additionally, try taking these two steps to refresh conditions across your account:
I will fiddle with the instructions to refresh and report back but in the meantime:
Re Switch: It is a managed switch. Cisco SG 300-10 gigabit switch.
The path within my LAN from the Nucleus+ to the FIOS quantum router goes through the SG 300 and then to the switch I have attached to the FIOS quantum router which is a Cisco SG 200 (also managed and gigabit) switch.
My wife has Norton VPN on her ipad and laptop. Could that really affect the path from the Nucleus+ to the FIOS router?
