Network Setup

I use my ISP's router alongside a personal router.

ARC Status

ARC is *Not Ready*

Roon Error Code

None of these are listed. It simply says "TIMEDOUT" or similar.

{
"ipv4_connectivity": {"status":"NetworkError","status_code":504,"error":"error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined"},
"external_ip": {"actual_external_ip":"72.aaa.bbb.ccc","actual_external_ipv6":"null","router_external_ip":"null"},
"natpmp_autoconfig": {"status":"NotFound"},
"upnp_autoconfig": {"server_ip":"192.168.86.1","found_upnp":true,"error":"s:ClientUPnPError718ConflictInMappingEntry"}
}

I believe uPnP is trying to configure your router to forward a port to the Roon Server that is alrready being forwarded to another ip address.

There are at least two possible reasons for this to happen:

  1. You Roon Server has changed ip address for some reason (has it been turned off?) and is now trying to forward the same port to its new address.

  2. You have another Roon Server or any other server which is already using the port assigned to ARC in Roon → Settings → ARC

The easiest way to fix this is probably to change the ARC port number in Roon → Settings → ARC. You can try setting it to any value in the range 1025 to 65535 that is not being used by any other internet facing server. Try changing it from 55000 (or whatever it is currently set to) to 60000 for example.

In the case of the first issue, you may also be able to fix it by rebooting the router that the Roon server is attached to.

Incidentally, the 192.168.86.1 ip address is unusual for an router handling the ISP connection. Do you have either a VPN or a MESH Wifi system?

In the case of the MESH wifi system, you should make sure that the secondary router(s) are configured for ‘Access Point’ mode. If you can’t do this, then you could also either:

  • Configure your ISP router to bridge mode (sometimes called modem only mode).
  • Configure a manual port forwarding rule on your ISP router to forward the port used for ARC to the MESH wifi router to which the Roon server is connected (The one with an ip address on the local network of 192.168.86.1).

@Elio_Concepcion, welcome to the Community. Your issue may be related to the port number ARC has assigned. based on the “ConflictMappingEntry” error message your posted. Please try @Wade_Oram’s recommendation by changing the port number for ARC and see if that resolves the issue.
