Description of Issue -
What is the exact port forwarding error message you see in the Roon Settings → ARC tab?
Testing Roon ARC access in Roon Remonte on my Windows PC failed:
This is the diagnostic data:
{
"ipv4_connectivity": {"status":"NetworkError","status_code":502,"error":"error: Error: connect EHOSTUNREACH 121.aaa.bbb.ccc:55000, response code: undefined, body: undefined"},
"external_ip": {"actual_external_ip":"121.aaa.bbb.ccc","actual_external_ipv6":"null","router_external_ip":"null"},
"natpmp_autoconfig": {"status":"NotFound"},
"upnp_autoconfig": {"server_ip":"192.168.1.1","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><faultcode>s:Client</faultcode><faultstring>UPnPError</faultstring><detail><UPnPError xmlns=\"urn:schemas-upnp-org:control-1-0\"><errorCode>718</errorCode><errorDescription>ConflictInMappingEntry</errorDescription></UPnPError></detail></s:Fault></s:Body></s:Envelope>"}
}
For ease of reading, here’s the error message contained in the above data:
<faultstring>UPnPError</faultstring>
<detail>
<UPnPError xmlns=\"urn:schemas-upnp-org:control-1-0\">
<errorCode>718</errorCode>
<errorDescription>ConflictInMappingEntry</errorDescription>
</UPnPError>
</detail>
Here’s the port forwarding that I set up manually on the router:
Note that Roon Arc is one of two port forwardings on the router. The other one works fine.
