z-way upgrade - website http://localhost:8083 unavailable

[webwonder]

I have tryed to upgrade z-way. Now I get the message from my browser, that http://localhost:8083 is unavailable.

The command
sudo service --status-all
show the service with a ? is this normal?
[ ? ] z-way-server

If I do that:
wget -q -O - razberry.z-wave.me/install | sudo bash
it looks nothing happens - I get no message - It takes only one second.

What can I do - (I'm a Linux beginner) ?

Linux Version:
cat /etc/os-release

Please do (choose latest date instad of XXXXX)
sudo mv /opt/z-way-server-XXXXX /opt/z-way-server
then restart Z-Way (or full Pi) and make upgrade again. That was a server side problem.
