Description of Issue

Hi. My roon remote on the phone and the tablet cannot find the core installed on the laptop. When trying to check the ARC in settings “Roon ARC” it gives the following date:

"{
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“188.ddd.eee.fff”,“actual_external_ipv6”:“null”,“router_external_ip”:“100.aaa.bbb.ccc”},
“status”: “status”: MultipleNatFound
,
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.0.1”,“found_upnp”:true}
}

This is the data I have received while trying to connect Roon remote and Roon ARC on my tablet and phone. What is the problem?

Hi
I’ve included the basic Multiple Nat Found troubleshooting tips below. But, in short, the first question is do you have 2 or more routers in your local network? And if the answer is no, then you should give you local ISP a call and see if you are on a CGNAT connection. If you are indeed on one, then you will need to ask your ISP if you can get a public facing IP address.

===========================================================

This can either be at the local-network level (commonly as a result of two routers), or at the level of your service provider (in the form of carrier-grade NAT).

If your setup involves an ISP-provided gateway (modem/router combination) and your own third-party router:

  • In the web administration interface of the ISP-provided gateway (modem/router combination), enable Bridge Mode or equivalent, where the ISP-provided gateway does not have DHCP routing enabled.

  • Alternatively, if you have already created a manual port forwarding rule in your 3rd party router, you can add an additional rule to forward the port through the ISP/second router.

If you only have one router in your setup or your modem is already in Bridge mode, please take a look through our list of known router and internet service provider solutions, as other users may have already encountered the same situation: ISPs and Routers: List of Known Solutions and Workarounds

You can reach out directly to your service provider to ask if they support port forwarding; this question will often enough to prompt them to explain whether or not the carrier-grade NAT they’ve implemented can function with ARC.

More specifically, you can pass along the following questions:

  • Have you implemented carrier-grade NAT for my account level?
  • Have you fully implemented IPv6, or do you have IPv4 addresses available?
  • Can I request a static IPv4 address to support port forwarding?
  • Are there any ports you have reserved at the ISP level I should be aware of?

If you’re unable to locate an existing solution in our ARC: Port Forwarding Resources subcategory, please reach out to the Roon 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?

In addition to what @Rugby wrote, note that the whole error is only related to ARC’s access to your Roon server from outside your home network.

If your regular remotes can’t connect within the home network, then this is an additional, unrelated issue.
