Plex Binding Error with Samsung TV

I’m setting up the Plex Binding, and have this working when I view on my Android Tablet. On my Tablet, things appear to work correctly. OH2 reports the move being played and within OH2 I can pause and play the movie.

But when I try this on my Samsung TV, OH2 shows the movie being played. But the OH2 controls will not pause or play a movie, and I see this error message in the logs. I know my TV is not at the web address 127.0.0.1, so I’m uncertain why it works with a Tablet, and not with Samsung TV.
