My Touch sees the nucleus but can’t connect to it. I’ve read to turn off LMS which I’m guessing is Logitech Media Server. Can’t get the touch to connect with or without lms running.
I take it you have turned on Roons squeezebox support in settngs ? Sometimes when I had my SB Radio I had to just reboot it or reset the Wi-Fi on it to get it to connect. Tbh the Wi-Fi chips on the touch and other SB devices are a bit archaic and start to fail after a while mine did completely in the end. Failing that restart your network gear and core.
