No connection to the web interface possible

I’ve just installed Volumio on my Raspberry PI 3. That has also worked well. Now I want to set up Volumio unfortunately without success I can not connect to the web interface. I get the message in Chrome The website has denied the connection.
can someone help me?

Sorry for this english it is google translator

Are you using the actual IP address or volumio.local?

I only use the IP which is at 192.168.0.5.
I just reinstalled Volumio so it worked then.
Now I have to somehow get from my PC sound to Volumio.
