Roon ARC "Not Ready" with Code 504 Error on Nucleus+ (ref#ERWHPN)

Support Nucleus Support
1

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

I am using a Nucleus+ server & Roon ARC keeps saying "Not Ready". I am using BitDefender Total Security's firewall and Roon.exe and RaatServer have both been allowed through the firewall. I have rebooted Roon operating system and Roon server and my Asus GT-AX1000 router & desktop computer. Upon trying to use Roon ARC it keeps saying "Not ready" It indicates a code 504 error. Can you help me to get Roon ARC working?

Describe your network setup

ISP is Rogers. Router is ASUS GT-AX11000 bridged to a Roger's supplied modem. I believe the Roon Server/ARC is running from my Nucleus+ server.

Hey @Greg_Johnson,

Thanks for writing in! Here are a few other things to test:

  • Turn on UPnP on your router and try to run Roon’s port forwarding test again.

  • Try to set up manual port forwarding in your router.

    • Make sure the IP/Port matches in any port forwarding rule you create.

  • Double-check to make sure you don’t have any VPNs, Firewalls, or other network filtering software blocking Roon.

  • Check if your modem is in Bridge mode.

  • Restart your network hardware and update firmware.
