Hi
Last time I have problem with app. It cannot find my Rpi... With web interface (PC) work.
I try to install app on other phone... Same. I do delete and reinstall app,... Same. I turn off Rpi, but same. I use last version of runeaudio. My net is: modem - switch (my PC who can connect to Rpi) - wifi-AP (with disabled DHCP)
Rpi is connected wih wifi.
