@docks can you post a screenshot or the text from the error message you see in Roon’s Setting → Roon ARC tab?

Hello @docks,

Thanks for posting.

To move this forward, we’ll need to take a closer look at how ARC is trying to reach your server.

Next steps

1. Please share a screenshot (or the full text) of the error shown in
   2.Roon → Settings → Roon ARC*
   This will tell us exactly which connection step is failing.
2. Enable diagnostics and reproduce the issue, then let us know the exact time you see the error so we can correlate it on our side.

About ARC connectivity (high level)

Just for context, ARC can connect to your Roon Server in a few supported ways:

• Port forwarding on your router (manual configuration)
• UPnP / NAT-PMP (automatic port mapping, if supported by the router)
• Tailscale (VPN-based connection, no port forwarding required)

Once we see the ARC status and diagnostics, we can confirm which path is currently being used and advise what adjustment (if any) is needed on your Orbi RBRE960.

Please post the screenshot and timestamp when you have a moment, and we’ll take it from there.
