Plex: Thumbnails are loaded but videos do not play; spinner stays on screen indefinitely Whether it is a Movie, Home Movie or TV Show, the thumbnails appear successfully, which means a connection to the Plex server running on my Mac is established.

However, when I try to play any video, the spinner appears and keeps on spinning but a video never plays.

This seems to be a common issue but so far I have been unable to find a solution.

Plex for Samsung 2.003

I may have found a solution.
