Network Setup

· I use a single personal router not provided by my ISP

ARC Status

· ARC is *Not Ready*

Roon Error Code

· None of these are listed. It simply says "TIMEDOUT" or similar.

System or third-party *firewalls *or *antivirus software* can sometimes block RoonServer from reaching ARC.

·
Try adding RoonServer and its associated processes to the whitelist of any firewalls or antivirus software you have installed, including the Windows system firewall, if applicable.
[You can learn more about firewall exceptions with Roon here.](https://help.roonlabs.com/portal/en/kb/articles/firewall)

Has the status in Roon -> Settings -> ARC changed after adding exceptions in your firewalls and antivirus software for Roon?
ARC is still *Not Ready*

Don't give up yet.

· I'm stuck. I'd like to create a post to ask Roon Community for help.

Hi @Andreas_Louwers,

ARC is not ready yet, and the timeout points to a network path issue between your Roon Server and the internet.

Let’s narrow down where that break is happening:

  1. Please open Roon Server > Settings > ARC and share exactly what the diagnostics screen shows there, including any status text or port information.
  2. Check whether you have port forwarding configured on your router, and if so, which port number is being forwarded to your Mac.
  3. Please share your router model/manufacturer and the mobile device plus OS version you are using for ARC.

Once you send the ARC diagnostics details, we can take the next step from there. Thank you!

In most cases, a “not ready” status in Settings → ARC arises from having two routers active in your network, or not having UPnP/NATPMP enabled in any routers. In some cases, port forwarding will be blocked by your internet service provider, in which case you’ll need to rely on Tailscale or an alternate solution. Here are a few resources to help you out:
