I I also have the same issue.
I have
Roon on and NUC 8i7 BNH Fanless
Connected by ethernet to Netgear Orbi 752 Mesh router
I have DSZ fiber router as the gateway to the internet.
The Orbi being a far superior Wifi mesh system is connected to the DZS fiber modem by Ethernet.
UPNP is enabled in the DZS Fiber modem
UPNP is also enabled on the Orbi
I recently shifted from Hong Kong To Mumbai - India
I had a similar setup in Hong Kong - albeit a different gateway router with NO IpV6 - Just IpV4
That is the only difference between the 2 setups and the system was perfectly working in Hong Kong
The present setup was Ipc6 enabled and the error reported is
{
“connectivity”: {“status”:“NetworkTimeout”,“status_code”:998,“error”:“”},
“external_ip”: {“actual_external_ip”:“110.aaa.bbb.ccc”,“actual_external_ipv6”:“3ffe:501:ffff:100:1e69:7aff:fe05:8532”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“10.0.0.1”,“found_upnp”:true,“error”:“<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/\” s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/\“><s:Body><s:Fault>s:ClientUPnPError<UPnPError xmlns="urn:schemas-upnp-org:control-1-0">501ActionFailed</s:Fault></s:Body></s:Envelope>”}
}
I have disabled Ipv6 on the gateway.
I have also tried enabling manual port forwarding but no joy
