Minimserver keeps 'disappearing'

[captainkev]

Greetings!

I've got an issue that the Minimserver that's running on my QNAP TS251A seems to only be intermittently visible on my LAN. I've got a feeling it's not a problem with minimserver itself, but more with the NAS or possibly the network.

When I search for Media Servers in either HiFi Cast app or in the Yamaha Musiccast app, sometimes both MinimServer and the NAS itself show up, sometimes only one of them, and sometimes none at all. Rebooting the NAS, router, switch or Wifi mesh sometimes fixes the problem, but more often than not doesn't.

Has anyone else had this problem, and if so did you manage to find the root cause? Could it be a problem with the NAS's own media server clashing with MinimServer? (I also have Plex running for movies).

My set up is:

NAS <-> Netgear switch <-> Mikrotik router <-> BT WholeHome WiFi <-> Devices

Any and all suggestions welcomed!
