Raspberry Pi 2 - Volumio & Kodi Plugin

Dear all,

i’m a really newbee to volumio, i have volumio on my rasberry pi2 up and running. Webradio and streaming from Andrioid works fine.
But now i have installed the KODI Plugin, this is also activated.
I haven’t changed the settings. So from my point of understanding. The Kodi Webserver should be reachable under port 8080.
so my Volumio could be reached under - so i thought i should receive the kodi webserver with - but this did not work.

Please could some one explain who i could connect to the KODI Webserver?

Thank you so much for your help.
