[Openstack] Dashboard VNC Console failed to connect to server

I'm getting forward here.
I installed nova-consoleauth
apt-get install nova-consoleauth
and I get these settings in nova.conf:
--vnc_enabled=true
--vncproxy_url=http://172.22.22.1:6080
--vnc_console_proxy_url=http://172.22.22.1:6080
--vncserver_listen=10.18.9.1
--novncproxy_base_url=http://172.22.22.1:6080/vnc_auto.html
--xvpvncproxy_base_url=http://172.22.22.1:6081/console
--xvpvncproxy_host=172.22.22.1
--xvpvncproxy_port=6081
172.22.22.1 being the 'public' NIC, and 10.18.9.1 being the private one
(for VM deployements)
Now, the command
nova get-vnc-console servername xvpvnc
gives me the url.
The error in the dashboard has changed. It now says it cannot establish
connection to 172.22.22.1:6080 (which is the noVNC port whereas I'm
using xvpvnc). So I guess I need to tell the dashboard to try on 6081.
Which setting is that?
