Volumio on Android Pi

Hello,

I am running Volumio on a Raspberry Pi 4B.

I have set it up with ethernet on my PC. Ideally I want to run Volumio on RaspPi with my Samsung Smart Phone running Android Pi.

Unfortunately the http Volumio local address is not recognised in my browser when I try and login via wireless. Is there something I need to set up within Volumio for this to work?

Thanks,

              Nevica
