Description of Issue -
What is the exact port forwarding error message you see in the Roon Settings → ARC tab?
The Roon core (version Roon ARC version 1.0.022) is not listening on port 55000 as documented in the ARC port forwarding FAQ. This makes it hard to set up port forwarding.
Below is the netstat information from the Roon core server.
servidor:/var/roon/RoonServer/Settings $ sudo netstat -n -l -t -p -4 | egrep -i 'roon|raat|arc|55000'

As you can readily see, the none of the Roon processes are listening on port 55000 as documented - and neither is anyone else. I haven’t changed the configuration from the default. I can’t set up the port forwarding rules without knowing which port I should forward. Apparently ARC Android client knows what port it is, but I can get ARC to tell me. There doesn’t appear to be a place in the configuration menu on my Android ARC app which tells me.
