Thanks, but as far as I'm aware I haven't connected via myQNAPcloud, which I did set up way back but haven't used in a very long while. All my devices are on the same network, connected by ethernet apart from the Android ones.
I seem to remember there was a fairly recent update to MinimServer, which I implemented as usual via MinimWatch on my desktop while I was busy with other work at the time. I saw the notice that the Raspberry Pi MS had successfully updated, but remember having a momentary doubt as to whether the QNAP one had. Is it possible that that update somehow failed to complete properly?
