While away I tried connecting via cellular and a stable Wifi connection (rental house, so I don’t know what the connection technology was). I’ll try the tailscale install, but I have an original Nucleus+. I don’t see that on the list of systems with tailscale pre-installed. Is there something I need to do first? And I have another VPN installed on my phone (rarely used) will Tailscale interfere with that?
So, is the only option to use tailscale and add hardware to my system? I’d hoped that by buying a Nucleus, it would stay supported. This was working earlier this year.
The latest early access update fixed Roon ARC for me using iPhone 13 Pro Max, Nucleus Rev2, and AT&T U-Verse router using port forwarding. I think the fix is included in the latest production release.
Try deleting and reinstalling Roon on your phone and rebooting your router, Roon server, and phone.
@Jim_F: Thanks for the idea – I’ll try it this weekend and hope it works. I’m not adding additional hardware, and Arc isn’t a requirement for me, but it sure would be nice to have for the times I’m away and want to access something.
If the Settings → ARC page lists a “Ready” status, then RoonServer can send/receive secure Roon traffic through the open port. This means ARC shouldn’t have an issue on cellular data unless your cellular provider is filtering downstream traffic (very rare).
The team implemented a fix in the last Early Access release for a highly specific condition that could emerge with IPv6 networks. This could possibly cause the symptom you were seeing.
However, the most common culprit for the “there’s an issue reaching your RoonServer” screen you’re seeing is an expired authentication between the ARC app and RoonServer. This happens when you do one of any three things: 1) restore a Backup, 2) reinstall/migrate to a new RoonServer, or 3) go about two weeks without syncing ARC to RoonServer on your home network.
The simple solution is to reinstall the ARC app as @Jim_F suggested. Please let us know if this helps.
Thank you both, it appears that ARC is now working for me after the re-install. Since I use it infrequently, I’m guessing I lost synchronization. Going forward I’ll do the uninstall/reinstall when I’m going out of town and plan to use ARC. But is there something less drastic that I could do every week or so to keep them in sync? Is it as easy as just starting up ARC on my phone once a week?
