ARC no connection (Vodafone Gigacube)

Roon Core Ubuntu LTSB Server

Vodafone Gigacube Router (Mobile, 4G)
Upnp enabled
There is no option for port forwarding.

“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“”,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“”,“found_upnp”:true,“error”:“Did not find UPnP service with WANIPConnection on network”}
