Roon ARC 'Not Ready' despite network configuration changes (ref#HJ1NI0)

[Anthony_Mazzella]

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 @Anthony_Mazzella,

Since you have a Windows PC, you can use Tailscale for NAT traversal instead of port forwarding. It’s far simpler than re-configuring manual rules in any router(s) you might have.

Tailscale Setup Instructions: Windows RoonServer

However, if you’d prefer to troubleshoot port forwarding, here are some thoughts:

Verizon doesn’t usually implement CG-NAT that blocks port forwarding, so the timeout is likely on your account end. Please share the full diagnostic snippet from Settings → ARC.

You only mention the FIOS router in your setup, but just to confirm - there’s no second router in this setup?

If you’ve created manual port forwarding rules instead of UPnP in your router setup, do they match the port number and IP address from Roon Settings → ARC?

Thanks!

Thank you for the fast reply.

I can confirm that it is only the Fios router in the chain
I have created both manual port forwarding rules matching the port number and IP address - and took the port from a designated open port in the 10k-65k range (specifically 10668)

I am open to Tailscale and will try that now.

For reference - below is the full error snippet. Thank you!

Managed to get it up and running with tailscale. Appreciate the assist!
