Description of Issue

I have a MacOS core: this is the error message below I get when I try to set up the RoonArc: any thoughts on how I might address this? I have my UpNp settings turned on per the troubleshooting tips but still nothing working: thanks

“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 think you need to create a manual port forwarding.

Take a look in the Roon App under Settings —> Roon Arc and write down the ip address and port number.

Take a look at the video below for a how to for a Fios Router (don’t know if it’s the same model, but hope the video helps).

Kind regards,

Hey @Frank_Barczykowski,

Following up on @Maarten_Duits’ suggestion, were you able to get port forwarding squared away successfully?

I’ll be here in case you need additional assistance :pray:
