Roon ARC error message
{

“upnp_autoconfig”: {“server_ip”:“192.168.50.1”,“found_upnp”:true,“error”:“doaction request return statuscode: UnknownError”}
}

can you explain to me in plain english What I need to do to get ARC connectivity?

btw: here’s what I see in my router’s WAN setup:

@support
It’s been a week since I posted.
No response?
It’s not a complicated issue. Just tell me what the Roon error message means in plain English.

See the help page, specifically

Less Common Errors
Miscellaneous UPnP error

on

The exact error is not there but it may be similar to this:

“found_upnp”:true,“error”:“doaction request return statuscode: ConnectFailure”} }

At least probably worth trying the fixes for this one

Yes, I’d seen that…
I put in port forwarding and a port trigger. Also tried a different port number. Didn’t change anything.




(obviously I’m not including the full source ip here, I tried it with and without source ip)
still got:

{
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“147.ddd.ggg.hhh”,“actual_external_ipv6”:“null”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.50.1”,“found_upnp”:true,“error”:“doaction request return statuscode: UnknownError”}
}

Still hoping to hear from @support

Menzies is also just a user doing his best. Roon support response times are rarely great but currently worse because they are understaffed. Expect more days :frowning:

Source IP will limit external access to requests coming from this particular IP. You probably don’t want that. (This setting is not supposed to be the router’s external IP. It limits from which external IPs on the Internet the router accepts connections)

You did double-check that your Windows machine with the Roon Core is at 192.168.50.250 and the Roon ARC settings expect port 55000 ?

Any firewalling on the Windows machine that might block 55000 ?

It’s also possible that it’s the ISP’s fault. See other Bezeq experiences here, maybe something helps?

In particular:

ARC now supports IPv6 with the regular production version. However, it doesn’t with all of them. I note that your ARC error message does NOT list a v6 address, so possibly Bezeq is not exclusively v6

Bezeq’s IPv4 is CG-NAT, which means you don’t get a real IP.
Look at the WAN IP your router gets in the status page. If it’s different from the IP you get using whatismyip.com than you’re behind a CG-NAT and port forwarding won’t work.

  1. Get a static IP.
  2. Get IPv6 to work.
  3. Use a VPN like Tailscale. That works great for me.

okay, why when I write @support does it automatically turn into @AMT?

Thanks I will try that.

I don’t think it does. As soon as you type @ it opens a menu with the user names that already posted in the current thread, to make it easy to pick one. Like so:

If you don’t want either, simply continue to write the name that you want. Then the menu shows additional known usernames from the forum (not just the current thread) starting with this character:

So I don’t have a real IP. Status page IP is different from whatismyip.
Means?
I should enable IPv6 in my router settings?
Set up a VPN on the router? Does it matter what type of VPN? Are there free VPN’s to setup on the router?
Can I setup a VPN just for Roon and not for the rest of what I’m doing?

again, @support
please chime in

tried using early access and ipv6 - didn’t help.
The ISP says they can give me a permanent IP after the weekend. Hopefully that will solve it.

got a permanent ip. My ISP says no IPv6 connection is possible. This is the error message I now get:
{
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“85.nnn.ooo.ppp”,“actual_external_ipv6”:“null”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.50.1”,“found_upnp”:true,“error”:“doaction request return statuscode: UnknownError”}
}
@support ever going to look here?
Any idea what to do?

Seems like your core tried to configure itself using UPnP and failed.
You can either enable UPnP and check if the core configures itself correctly, or enable port forwarding to the core.
Just make sure that the core will always have the same IP in the network.

Yep, thanks.
Port forwarding now works. And I can play my library with ARC on my phone over my cellular data link.

I have my core setup with a static IP on the home network.

Still bugs me that support doesn’t look at these posts.
I’m very glad for your help and the others also, but Roon support should chime in on this stuff. It would probably taken me much less time to get a solution if they had…

Thanks again.

Meh.

This is a technical issue that official support doesn’t always want to mess with. Roon is technically advanced as it is.

זה מה יש.

It’s not that they don’t want to. It’s just that they are slower working through threads than customer patience often lasts. Staffing issues as I already mentioned

Yeah, I don’t really buy that about support.
The OP was 2 weeks ago; no one at support even viewed the page and said “we’ll get back to you”.
They’ve said in the past they want to help people with ARC. If they don’t want to, they shouldn’t have it in the “support” category of the forum.
Label it “support from the community”
