ARC stopped working out of the blue

Support ARC: Port Forwarding Help
1

Hi. ARC was working until yesterday. Now, I get this error:

{
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:502,“error”:“error: Error: connect EHOSTUNREACH 76.aaa.bbb.ccc:55002, response code: undefined, body: undefined”},
“external_ip”: {“actual_external_ip”:“76.aaa.bbb.ccc”,“actual_external_ipv6”:“null”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.0.1”,“found_upnp”:true,“error”:“doaction request return statuscode: UnknownError”}
}

Would you please help? Thanks.

Description of Issue -

What is the exact port forwarding error message you see in the Roon Settings → ARC tab?

This is an unspecified UPnP error on the router. Try restarting the router and then (when it is fully back up) the Roon server machine.

Thank you. I rebooted the host, and now it works.

Hi @Andrew_Stein !

Glad you were able to figure it out.

We’re closing this topic then.

Feel free to reopen it in case you have the problems again.

Regards.
