Description of Issue -

What is the exact port forwarding error message you see in the Roon Settings → ARC tab?

Roon ARC connection to core is not working. I am connected to a fiber, but the external IP on my router is private (the 46.aaa.fff.ggg visible below is a public IP of the provider, mine is private starting with 100…). How can I make it work in this configuration.

{
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:502,“error”:“error: Error: connect ECONNREFUSED 46.aaa.fff.ggg:55000, response code: undefined, body: undefined”},
“external_ip”: {“actual_external_ip”:“46.aaa.fff.ggg”,“actual_external_ipv6”:“null”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“10.0.1.1”,“found_upnp”:true,“error”:“doaction request return statuscode: UnknownError”}
}

@Radoslaw_Kuczynski, the diagnostics you’ve provided suggest that UPnP is not properly configured on your router.

Please first try the following steps:

• Try to enable UPnP/NATPMP in the web administration interface for the router directly upstream from your Core
• Try to manually open the port in your router’s port forwarding configuration
• Make sure the IP/Port matches the Port listed in Roon → Settings → ARC
• Check for any VPNs or Firewalls that might be interfering
• Check if your modem is in Bridge mode

If you continue to experience difficulties, please tag the support team and include the following information:

1. What is the make and model of your modem and router?
2. Do you have any additional network hardware, like additional routers or managed switches?
3. Who is your internet service provider and what is your geographic region?
4. Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?
