Network Setup

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

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?

· UPnP is not listed in my router settings

POSTING MY DESCRIPTION FROM THE FORUM ALONG WITH ERROR
I had posted some time ago regarding my issue with ARC not connecting while it is at a remote site. I never got around to troubleshooting it. I just left it as is so when I return home (which I have) I can just plug it in and pick up where I left off. Problem is I am now having the same issue as I did off site. Nothing has changed between my NUC or my router. It worked just fine before it left. ARC could see my local library just fine. In the older post, it suggested I use Tailscale.For all intents and purposes, I shouldn’t have to since I did not have to in the first place???

It does not look like I can post pics here so what I will do is a short video of what is going on and what I have tried so far. Again it worked perfectly, without 3rd party intervention beforehand. Something has changed.

here is the error code:

{
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error code: 504
”},
“external_ip”: {“actual_external_ip”:“75.aaa.bbb.ccc”,“actual_external_ipv6”:“null”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.50.1”,“found_upnp”:true,“error”:“s:ClientUPnPError718ConflictInMappingEntry”},
“multinat_autoconfig”: {“status”:“Failed”,“error”:“Router Control URL not found”}
}

Hi @David_Rice,

Thanks for laying out the error details. The “error”:“s:ClientUPnPError718ConflictInMappingEntry” message means something else is already using that port.

Please try changing the port in both Roon Setting → ARC and your router, then see whether that clears the conflict. If it does, ARC should be able to complete the connection again.

Let us know what you see after that.

Hi @David_Rice,

We wanted to follow up on our previous message. Please try changing the port in both Roon Settings for ARC and your router, then see whether that clears the conflict. If it does, Roon ARC should be able to complete the connection again.

Let us know what you see after that. Please also note, if we don’t hear back from you, this thread may automatically close. If this happens, you can reopen the thread by submitting a reopen request:

Thanks!
