Description of Issue -

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

i was getting the following error:

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

I manually configured my firewall to forward port 55002 which is the port that Roon Core is configured to listen on. I still was getting the error.
The solution- reset Xfinity router to factory default, re-enable bridge mode and setup tcp port forwarding to the ip address of my Roon Core PC.
Roon ARC is connectig now.



Thanks for letting us know that you got ARC to work, happy listening!
