Autoshutdown Plugin does not check for docker ports

I use the autoshutdown plugin, to shut down my nas if it is not used. Also I have multiple dockers running on the nas with different ports for each.
Now the autoshutdown plugin detects if i connect to the omv gui via port 80 just fine. But the access to, for example my logitech media server docker with port 9090, is unnoticed by the plugin, as well as all other docker ports I use. Is there anything I can do, that the autoshutdown plugin detects if somebody is connected to a docker container?
I made sure, that I have all used ports listed in the sockets field of the plugin.

Kind regards,
Patrick

Actually the container ports are not recognized. I looked at the output of the command ss -n, which is used by the autoshutdown command for port activity detection. The ports for my containers don't appear there. I will have a look at the docker documentation to see if I can find some advice there.
