Because i so often have problems with connecting to my rasperipi i would change dns so set it to 1.1.1.1 and 1.0.0.1 and after this it will not run in browser anymore 
What do I do ?
Maybe i have done it wrong.
You need the DNS to work internally, on your LAN or WLAN, so the DNS server in your router is the correct address to use as the gateway and DNS server.
External DNS servers such as Google’s will not know or resolve your internal LAN addresses and cannot find your Volumio.
EG. Your router is the DHCP and DNS server for your LAN network of
192.168.50.x
Router would probably be 192.168.50.1 - Use this as gateway and DNS server
By default the internal DHCP server of the router will take care of this for you and hand out the correct config to hosts on the internal LAN.
I manage to make it work again but thanks
