(also posted on unifi networking forums)

Long term Squeezebox and unifi networking user. No issues with squeezebox touch connecting to my normal unifi access points (ac-pro).
Recently added an additional unifi nanoHD access point. All other clients 'close' clients connect to it. However my squeezebox touch will flat refuse to connect to wifi when it's powered on.

I power off the nanoHD, leaving the remaining ac-pro access points in place and it's happy to connect.

All points are on same SSID (it's unifi, isn't it!) with a good spread across bands on both 2 and 5G.

Any thoughts appreciated. Seems to be unique to the touch. Have also tried a factory reset with no impact.
