You can see 3 or 4 of the above client disconnects in a row leading up to the playback actually stopping - these are also happening at other times but as you’re not also flagging those as dropouts I would guess that plex is able to recovery in those instances.
You need to work out why your FireCube is having a periodic grouping of dropouts within the space of a few mins… Could be bad wifi, could be overheating and, could be other background apps running on it consuming all the resource etc.
