Hello @Phil_Kemp,

Thanks for reaching out and sharing your question with us.

We have reviewed the diagnostics from your machine, and we have two main findings to discuss with you:

  1. Roon ARC Connectivity (CGNAT) It appears that your internet connection is currently behind CGNAT (Carrier-Grade NAT). This means your ISP is sharing a single public IP address among multiple customers, which prevents Roon ARC from establishing a direct connection to your Core.

To resolve this, you have two options:

  • Option A (Recommended): Contact your ISP and request a static public IP address. (Many ISPs offer this for a small monthly fee).
  • Option B (Alternative): Use a VPN solution like Tailscale to bypass the restriction. You can find our setup guide here: [url=https://help.roonlabs.com/portal/en/kb/articles/tailscale-setup-instructions-windows-roonserver]Tailscale Setup Instructions[/url].
2. Local Audio Devices Regarding your local audio zones, the diagnostics did not provide enough information for us to pinpoint the issue.
  • Screenshots: Could you please share a screenshot of your Settings > Audio tab?
  • Details: What specific audio devices are connected to your Windows machine?
  • Drivers: Do you have any proprietary audio drivers or software installed (such as ASIO drivers, Nahimic, or specific manufacturer control panels) that might be taking exclusive control of the audio device?
Looking forward to your reply so we can get both of these sorted for you.

Thanks.

Hi @Phil_Kemp,

We’re going to need a little more information to take any effective action this thread.

Your post mentions that you might have issues with RAAT connectivity (locally-controlled audio devices). This seems to be the same issue you encountered before here:
https://community.roonlabs.com/t/music-stops-playing-midway-through-track-on-roon-client-for-windows-11-ref-wt6j17/270465/5

Can you share a brief overview of your network topology? Is your RoonServer relying on ethernet or on WiFi?

i finally solved it. across the board updates were failing. i removed the lock files on the server rebooted and tried the updates. didn’t work.

Ended up reinstalling manually. that is currently working.

you can close this for now.

Phil
