Thanks for writing in, it’s great to see you on community again.
I was able to take a look at your account, and see that your Ayre qx5 is showing as Roon ready within your Nucleus devices, are you still having issues here?
If you’re still having issues, I’d also give your router as well as Nucleus and the qx5 a hard reboot and leave them unplugged for a few minutes before powering back on.
If issues still persist, reinstalling the most recent firmware on the qx5 may help.
