Broken OH after openhabian-config to upgrade from 2.1 to 2.2

So, I started of with openhabian on pi2 (from the image installation).

Today I used the openhabian-config to upgrade from 2.1 to 2.2, but…
Pi boots up normally, by :8080 is an unreachable site.

Service is running:
● openhab2.service - openHAB 2 - empowering the smart home

CGroup: /system.slice/openhab2.service
└─669 /usr/bin/java -Dopenhab.home=/usr/share/openhab2 -Dopenhab.c…

What can I diagnose?
