Network Error 502 when accessing Roon ARC with Netgear Nighthawk (ref#5OTPMU)

Support ARC: Port Forwarding Help
1

Network Setup

· I use a single personal router not provided by my ISP

ARC Status

· ARC is *Not Ready*

Roon Error Code

· “natpmp_autoconfig”: {“status”:“NotFound”}, “upnp_autoconfig”: {“status”:“NotFound”} }

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 @paulhewitt1968,
Welcome to the Roon community! I’m sorry that a problem is what brought you here, but we’re glad you reached out.

The error message you posted indicates that Roon wasn’t able to automatically configure port forwarding on your network. Fortunately, there are two ways you can resolve this:

  1. Use Tailscale to connect ARC to your server. This is the simpler option for many users since it doesn’t require changing any router settings. You can follow this step-by-step guide to get set up.
  2. Manually configure port forwarding in your router settings. This involves creating a rule to allow external connections to reach your Roon Server. This article walks you through the process. If you run into any trouble while setting it up, feel free to share a screenshot or any specific questions and we’d be happy to assist further.

Let us know which option you’d like to pursue or if you need more clarification. We’re here to help!
