Web console restriction

[Louis garcia]

My server has four interfaces and I am trying to restrict cockpit to only listen to one of
them. I am running fedora 30 with cockpit 202.1. I added listen.conf to systemd as the
docs says.
is web console buggy ?

$cat /etc/systemd/system/cockpit.socket.d/listen.conf
[Socket]
ListenStream=
ListenStream=172.16.0.1:9090

When I ssh in I get:
Web console: https://172.16.0.1:9090/ or https://24.51.220.122:9090/

But cockpit only listening on 172.16.0.1:
$ss -lntu
tcp           LISTEN         0              128                       172.16.0.1:9090     
                  0.0.0.0:*
