Description of Issue

ARC test gives me the following error code

“connectivity”: {“status”:“NetworkTimeout”,“status_code”:998,“error”:“”},
“external_ip”: {“actual_external_ip”:“xxxx”,“router_external_ip”:null},
“natpmp_autoconfig”: {“server_ip”:“”,“found_natpmp”:true},
“upnp_autoconfig”: {“server_ip”:“”,“found_upnp”:true,“error”:“Did not find UPnP service with WANIPConnection on network”}

Tried setting up a manual port forward but no luck. Not a networking guru so - Any suggestions?

What modem? Who is your ISP?

Modem is Cisco dpc3010 and ISP is Pentanet (Australia)

Modem via Ethernet to Orbi base and also to same base is Sonictransporter Audiophile which runs as Roon core
