Roon ARC not ready after attempts to restart and reconfigure (ref#HC1B3W)

[irwin]

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.

Describe the issue

Roonarc was working but suddenly came up not ready. I've restarted the service on synology where the core is, restarted the nas, restarted the router, deleted the port forwarding and readded it, turned off upnp and back on. Tearing my hair out !

Describe your network setup

Is it possible that your ISP has switched to using CGNAT?

Can you post a screenshot of the diagnostics message screen in Roon Settings/ARC?
Should look something like this (there should be a “copy” button on the message edge):

was going to on the original post but hit enter too quickly and couldn’t work out how to get back in !

[irwin]

Hm. Don’t know what that is but I’ll investigate

Ah, here we go

How to set up Port Forwarding and bypass CGNAT

Last Updated: Monday 14 Aug 2023

Does Aussie broadband use CGNAT?

Yes – CGNAT (Carrier-Grade Network Address Translation) is used on our broadband services and is typically enabled by default. This means that your public-facing IP address is often shared with other users, which is necessary to avoid running out of limited IPv4 addresses.

I’ll contact my ISP and see if disabling it helps

[irwin]

Success!!! I had not heard of CGNAT but asked my ISP to turn it off and hey presto - Roon arc is working again. Thanks @DDPS and @bearFNF for your help.
