... would you like to use a different player?
I get this all the time. I'm running a nVidia Shield Android TV for my Plexus server, and as my default plexus player.
This error occurs when I'm logged on to plex, in the Plex app on my shield TV, with both my server and client apps up-to-date... Any ideas?
Is it possible to need to open some ports on my router to make my Echo and Shield see each other more clearly?
