I have downloaded the new Roon ARC , am unable to securely connect.

I checked my router and Upnp. is turned on.

I tried temporarily turning off firewall on my router and Computer but made no difference.

Here is a copy of posted error codes.

“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”: {“server_ip”:“”,“found_upnp”:true,“error”:“Did not find UPnP service with WANIPConnection on network”}

Can anyone help with a solution please.

Thank you
