[SOLVED] Pi/moOde non-responsive after inactivity - suggestions?

[the_bertrum]

Is the wifi to the zero on the weak side? I find that the poor signal to my Pi3 inside an old radio can make the mDNS a bit hit and miss. I reserve the IP on my router, and address the player using that instead, which bypasses the mDNS and therefore the instability.

If you can access via IP in the non-responsive state, that could be your answer too.
