Network Error 502 due to UPNP and NAT-PMP Configuration (ref#BRMFGD)

Support ARC: Port Forwarding Help
1

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?

· I've turned UPnP/ NAT-PMP on and ARC won't connect

Select the Diagnostic Keyword or Text String

· Something else

Don't give up yet.

· I'm stuck. I'd like to create a post to ask Roon Community for help.

Describe the issue

Initially the ISP router’s setting originally prompted the error: UPNP and NAT-PMP

Currently it has changed to

{
"ipv4_connectivity": {"status":"NetworkError","status_code":502,"error":"error: Error: write EPROTO 140046065878976:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:332:
, response code: undefined, body: undefined"},
"external_ip": {"actual_external_ip":"116.aaa.bbb.ccc","actual_external_ipv6":"null","router_external_ip":"116.aaa.bbb.ccc"},
"natpmp_autoconfig": {"status":"NotFound"},
"upnp_autoconfig": {"server_ip":"192.168.X.XXX","found_upnp":true}
}

Describe your network setup

Hi @crim_tears,

I’d first try creating a manual port forwarding rule in your router settings, using the port number and IP address listed in Roon Settings → ARC.

Some Singtel users have reported that their dynamic IPv4 assignment can block port forwarding. If you’re still having trouble after creating a manual rule, then I recommend trying Tailscale as an alternative for NAT traversal:

Please let us know if this helps!

Hi @crim_tears,

We’re not able to confirm from diagnostics whether you’ve successfully circumvented the double-NAT blocking your RoonServer connection to ARC.

Have you tried creating a TCP manual port forwarding rule in your router, matching the port number and IP address in Roon Settings → ARC?

If you’ve not been successful with port forwarding, I’d encourage you to setup Tailscale instead. You’ll need to install the app on both your RoonServer machine and the phone with which you use ARC.

Please visit the link above for specific Tailscale instructions. We’ll watch for your response. Without any post from the OP, this thread will automatically close after several days. Thank you!
