Plex Web stops buffering after 2 mins causing playback to stop

@ChuckPa apologies, only now did I get dragged into this thread as it was linked elsewhere (unsure if it’s the same issue as my original thread here - Plex video stops consistently on browser, not on app - #9 by sykogee) but the content I’m playing is not especially high quality. It’s a 720p video, fairly standard containers, and used to work well in the previous web version - and works well in the desktop player.
