Description of Issue -

What is the exact port forwarding error message you see in the Roon Settings → ARC tab?

below was the error data. another thing is the ip showed in Roon settings is actually not the ip address of my computer, so I wondering that may be a issue.
{
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:502,“error”:“error: Error: connect ECONNREFUSED 103.aaa.bbb.ccc:55000, response code: undefined, body: undefined”},
“external_ip”: {“actual_external_ip”:“103.aaa.bbb.ccc”,“actual_external_ipv6”:“null”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“status”:“NotFound”}
}

the error code turns to:

{
“ipv4_connectivity”: {“status”:“NetworkTimeout”,“status_code”:998,“error”:“”},
“external_ip”: {“actual_external_ip”:“219.ddd.eee.fff”,“actual_external_ipv6”:“null”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“198.19.1.1”,“found_upnp”:true,“error”:“<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/\” s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/\“>\n<s:Body>\n<s:Fault>\ns:Client\nUPnPError\n\n<UPnPError xmlns="urn:schemas-upnp-org:control-1-0">\n501\nPAL_UPNP_SOAP_E_ACTION_FAILED\n\n\n</s:Fault>\n</s:Body>\n</s:Envelope>\n”}
}

please help, thxxx a lot.

Hi @Peter_Qiu,

Thanks for taking the time to write in, and I’m sorry to hear you’re having issues getting Arc up and running.

As a first next step, could you please attempt to use a different port number in your Roon Settings> Arc?

For example, I’m currently using 55002, let me know if the same issue occurs for you. Thanks!
