Description of Issue
After upgrading my Mac Mini to Catalina, I found Roon updated to 2.0. (Oddly enough, USB no longer shows up as an output option; I have to use System Output and configure Sound in the core’s settings to go to xCORE USB Audio 2.0 Output).
Going to Roon ARC, I get Not ready. It shows Roon Core IP as 192.168.0.9 and Port as 49454.
At one point, the error message was the one in the title, but at this point, the diagnostics data read
{
“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“75.164.17.64”,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“status”:“NotFound”}
}
I have attempted most of the fixes listed. Specifically:
Turned UPnP off and then back on.
Added port forwarding:
Port Forwarding List
LAN IP Protocol Ports Forwarded Remote Defined
192.168.0.82 TCP 5500 No
Disabled firewall for IPv4 on router temporarily and disabled firewall on core machine.
Verified that firmware on the modem was up to date.
I tried from a laptop on the network running a port scan on port 5500 and it shows the port as closed (don’t know if that’s expected or a problem).
Thank you for your support. I am very excited about this feature; I am going to drive across the country in three weeks and would love to have Roon go with me!
