I love Plex, and for some reason paid for the Plex pass, and one of the greatest benefits of doing that seems impossible. My remote access settings say not available outside my network. But somehow, I get a very slow and lousy connection when I AM outside my network. So...I guess it works..kind of. Now, with our new Echo Show, after pairing them up...echo just says that my server is online but remote access is not enabled. I'm really not sure what to change in my settings. It only seems to work with the manual port enabled. Other than that...I get this message from Plex settings.
