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”:“xxx.xx.xxx.xxx”,“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.
