Roon ARC stopped working since yesterday (ref#QXGW8P)

[Raymond_Sir]

Network Setup

· My only router was 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?
I don't have any system or third-party firewalls or antivirus software.

Have you successfully located and enabled the UPnP or NAT-PMP settings in your router's web UI?

· I've turned UPnP/ NAT-PMP on and ARC won't connect

Select the Diagnostic Keyword or Text String

· Something else

Don't give up yet.

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

Hi @Raymond_Sir,
Thanks for reaching out to us about this issue. I’m going to need some more details before I can begin to help you troubleshoot.

1. Can you share a few screenshots of what you see when you try to use ARC?
2. Please share the full error from Roon settings → Roon ARC.
3. Does ARC work if you use it while your phone is on your home network?
4. Have you made any changes to your home network recently?

3. Arc works well if I use it while my phone is on my home network.
4. No changes have been made to my home Xfinity Gateway Router.
   Thanks,

Hi @Raymond_Sir,
Based on your answers it seems that automatic port forwarding failed . You have 2 options for connecting ARC to your server. You can either set up port forwarding manually or use Tailscale instead. For manual port forwarding you can follow this article. For Tailscale you can follow this guide. Most of our users find Tailscale the easiest.

If you need any more help let us know!
