After updating to Roon 2.71 Build 1679, ARC fails to work. Furthermore, ARC 1.81 Build 424 does not show up in TestFlight.

{
“ipv6_connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error code: 504\n”},
“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error code: 504\n”},
“external_ip”: {“actual_external_ip”:“59.hhh.iii.jjj”,“actual_external_ipv6”:“240d:aaa:bbb:ccc:ddd:eee:fff:ggg”,“router_external_ip”:“null”},

“multinat_autoconfig”: {“status”:“Failed”,“error”:“No uPnP Routers found on LAN”}
}

If ARC was working previously and able to reach your Roon server, try changing the port number used by ARC. I had to do this a few days ago as the old port number was no longer reachable/usable and the http error code shown was also 504.

Thank you for your comment. I did change the port number several times but no luck.

Followed by restarting Roon (and updating port forwarding rule on router if needed)?

It did work after restarting Roon according to your suggestion. Thank you very much for your kind help!
