Description of Issue

In testing Roon Arc with my T-Mobile 5G Home Internet Gateway, I’m receiving a “Not ready” error with the following diagnostics data:

{
“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“xxxx”,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“status”:“NotFound”}
}

I don’t know whether or not it is possible to enable UPnP or NAT-PMP with this Internet gateway as the settings menu is extremely basic and doesn’t list anything related to advanced options such as NAT or port forwarding. Please bear in mind that this is a modem, router, and access point combined in a single device which connects to the Internet using T-Mobile’s cellular network in the US.

Thank you for your help.

Unfortunately it may be that TMobile 5G does not provide a routable external IP address. I know that this is true for many cell carriers with traditional WWAN routers. Also in general, it may be simpler to just manually configure port forwarding. That’s what I did with Xfinity Cable and my Untangle FW. Works great!

Same issue. I’d appreciate a step-by-step workaround, as I’m definitely not an IT person.

Same issue. Any help would be appreciated.
