Description of Issue

Roon says the setup is working fine as you can see below:

When I first loaded Roon ARC on my Android Auto system it said “connecting with Roon Core for the first time” and spent some time working on it but then locked up. I restarted it and it said “last time connected to Roon Core 1 minute ago” and then said something like “Your Roon Core is not configured for external access.”

I installed Roon ARC on my phone to see if it would work better but it won’t even start on my phone (Pixel 7 Pro). I just see the Arc logo and nothing happens after that. I know I have a good connection since it only took seconds to download Roon ARC plus Qobuz and Tidal play fine.

What does it mean that the “…Roon Core is not configured for external access” when the Roon ARC test specifically states that it is configured for secure remote access?

Try rebooting the Roon Core if you haven’t.

Thanks for the response. I rebooted ROCK but to no avail. It’s acting as though ROCK is refusing to auth or perhaps is refusing the connection. I have the port forwarding set to the internal IPv4 address but do I need to do regarding the IPv6 connection?

Try turning off IPv6 in your router - that seems to have been the trick for at least one brand of router…

BT Smart Hub 2: IPv6 Will Prevent Port Forwarding [Solutino: Disable IPv6 in BT Modem Settings ]

I’m struggling to get port forwarding to connect. My network topology is router (BT Smart Hub 2) connected via ethernet to a switch; Intel NUC running ROCK is also connected via ethernet to that switch. Router broadcasts wifi also. I’m trying to connect using Roon running on a Windows PC which is connected via ethernet to the switch. But the Roon Mobile settings shows that it’s not connected: [image] It also doesn’t show the Roon Core IP (I don’t know if this is expected)? Looking at the R…

Edit: although now I see that you’re using Starlink - where IPv6 is a requirement - so perhaps the trick for you is to see if port forwarding can be done for IPv6 (which I think is actually a contradiction in terms - so frankly, I’m just guessing…)

Hey @Dean_Kimball,

Ben with the support team here, I wanted to check in on this thread to see if you were still running into issues getting Arc up and running?

You may find this step by step thread helpful if you haven’t come across it yet:

How to make Roon ARC connect to ROCK over StarLink without a VPN

For StarLink users who want to use Roon ARC to connect with ROCK, here is the solution: Make sure you have been allocated an IPv6 address by Starlink. You can use test-ipv6.com or a similar site to do this. If you don’t have an IPv6 address then check your router to make sure you have IPv6 enabled. You will need the Starlink LAN adapter and have your Starlink router bypassed to some other router (I have an Asus RT-AX3000). If you are getting a new IPv6 address you will lose connectivity until …

I’ll be on standby for a status update!
