Roon Arc connection fails

Support
1

Roon Arc was unable to securely access my Roon Core and I got the following message:
{
“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“78.xxx.xxx.xxx”,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“status”:“NotFound”}
}

The UPnP service is not activated on your router. Therefore Roon cannot automatically configure the “port forwarding” to enable access.

That’s why the message says “upnp_autoconfig”: {“status”:“NotFound”}

You must either activate the UPnP on the router or, alternatively, manually configure the port forwarding on your router.

By the way, you probably don’t want to show your actual external IP address on a public forum

Hi @Udo_Schmitz

It looks like the best possible advice was given by, @Suedkiez

Please let us know if you’re still experiencing issues after setting up port forwarding. In the meantime, here is our canned response for 504 errors.

Thanks,
Wes

Thank you for your patience while we’ve diligently worked to reach every request for support with port forwarding. 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?
