UPnP ARC issue on router (ASUS AC68U)

Support
5

I have ASUS AC68U router.
I have UPNP already enabled and i manually forwarded the port.
It cannot connect to Roon ARC.
Should I copy the diagnostic data from the Roon ARC tab in Roon Core here?

Edit. And I deleted the ext IP:

{
“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:"XXX,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“status”:“NotFound”}
}
