Naim App no longer picking up Minim server

[Donuk]

This may not be relevant, but....
I have found Devolo extension plugs to be quite moody. I do not use them on my hifi network, but elsewhere. They seem rather sensitive to where they are plugged in, e.g. not in an extension block. Incidentally if you can download a Devolo app, for a Mac, that will actually pick up anything on your network, you are better than I.

Try getting a long ethernet cable and avoiding the Devolo by way of experiment.
