Hi - when I log into Roon from my iMac, it tells me it can see Roon server on my QNAP NAS, but after that it just hangs with the animated speaker symbol. The NAS is new but since the remote can see it, something is clearly not connecting in the way it should. (It did connect just fine when I first got it, but once it tried to back up everything stopped working). I've set file sharing up for SMB but don't see anything else that's odd. All help greatly appreciated. Many thanks.
