Roon ARC lost all connectivity about a week ago. I deleted and reinstalled the app, and I can now connect from inside my home and even outside (before, I could not). What I still *can't* do is connect inside my car via CarPlay, which is unfortunately where I use Roon ARC 99% of the time. This issue seems similar to the one I last reported last June. What you mentioned then seems likely now: "A Roon background update during those two weeks is causing a session mismatch with ARC and your RoonServer."
Hi Kevin, from your description this actually sounds very much like it maybe an issue of your vehicles infotainment system. I’ve had to reset mine as well in order to resolve my connection issues.
It takes just a few seconds/minutes to perform. Here’s an excellent video I just located. Give it a try.
Periodically you may experience issues with your Bluetooth in your vehicle as well. If you’re vehicle doesn’t push out an upgrade performing a reset on the infotainment system can often do just as well at resolving connectivity issues.
Thank you very much for this. I will give it a try. Everything else is working via CarPlay, though. The current situation is very similar to what happened six months ago, and that seemed to require some kind of reset on Roon’s end. Anyway, we’ll see!
Thank you for the report. Please let us know if resetting CarPlay has had any effect.
Diagnostic logging from your ARC account shows that ARC has paired successfully with CarPlay in the last several days on multiple occasions, but that the phone experienced interruptions with connectivity around the same time. ARC was paired to the Infotainment system but it was encountered poor service.
What is the specific symptom you see in CarPlay? What about in ARC? Are there any error messages presented?
Logs show ARC had become unauthorized and reinstalling associated the app with your current RoonServer. Had you migrated your RoonServer or restored a Backup recently?
No luck with re-setting CarPlay. As I mentioned to Singleton, everything works with CarPlay except for RoonARC. I did not migrate the server or restore the backup. The reinstallation of the app now works everywhere but inside my car. Error messages are “poor connection”, or, sometimes, “unauthorized”, or “something went wrong”.
UPDATE: I checked my car again and saw that there was an audio software update that needed to be downloaded and installed. Hoping that that would be the solution, I did so, but it did not change anything.
So, a summary of where I am:
Apple CarPlay works with literally everything I connect to it in my car (Waze; YouTube; Spotify, etc.) except for RoonArc.
When I try running RoonARC, it will not load my albums or playlists; it just continues to read something along the lines of “loading, please wait”.
When I try to play some music, the app spins its wheels and then gives me either a “poor connection” message or a “cannot connect to Roon server. Check your Roon server and try again” message.
Could my recent OS “upgrade” to Sequoia on my desktop computer have anything to do with this? That does seem to be when the trouble started, now that I think about it. But I can’t be sure about the timing.
Sequoia does have tighter network security than previous MacOS versions. Navigate to Privacy & Security in your System Settings. There should be “Local Network” tab. Toggle on Local Network access for RoonServer.
The error snippet you’ve pasted means that RoonServer can see the router’s port forwarding service (UPnP) but can’t connect automatically. This is possibly due to the Sequoia restrictions, so first test that.
If you’re unable to access your Spectrum router settings, then I would suggest using Tailscale instead of port forwarding. It’s as simple as installing the Tailscale app on your Mac and phone.
Please see here:
Are you able to login to ARC successfully on your home network (WiFi) if you reinstall the app from scratch?
Step 1–Local Network settings: I checked, and RoonServer was already selected. I de-selected and re-selected it. No effect. The error message on Roon remained.
Step 2–Tailscale: Installed (and I also deleted and re-installed the RoonARC app). Both are up and running. I was able to log in to my home network, and RoonARC works inside my household (e.g., listening on my mobile phone while in another room). I will test it in the car on Monday when my work week and commute resume, and will then report back.
