Roon ARC displays 'Not ready' with Network Error 504 (ref#M83E0S)

[Mads_Hesselbaek_Oles (Mads Hesselbæk Olesen)]

Network Setup

· I use my ISP's router alongside a personal router.

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 your network setup

I have bridged the IPS (Type Zyxel NR5103EV2 5G) because I use Orbi type RBR50 with one satellite for Wi-fi. My Roon core is an Innuos Zenith streamer which is ethernet connected to the Orbi RBR50. No firewall.

Hello,

I have the same problem. Have read the ‘Port Forwarding’ info. I did not
understand it. More important the steps to take assume I know and understand the jargon.

Hi @Mads_Hesselbaek_Oles,
Thanks for reaching out to us about this issue. That error indicates that automatic port forwarding was unsuccessful for you. You have 2 options here. You can either manually set up port forwarding or use Tailscale instead. I would advise taking the Tailscale option as it is a lot simpler and doesn’t require changing any settings in your router. You can follow this article if you want to use Tailscale.

If you want to continue with port forwarding the first step would be to put one of your routers into bridge mode and then set up the port forwarding rules manually. If you decide to do that and need help please let us know!
