Why can't I play media on any devices within my Home?



I am a long time Plex user and have not had any issues until about 3 days ago when my Plex clients stopped playing content. The server seems fine. I can open up a web browser on the server itself and the content plays fine there but if I try to play media on my Fire Stick, IPad, iPhone or Samsung Tv, the content just won't load. I just keep getting that ring turning round and round. The clients can see the catalog and it seems to be updating the catalog fine but just won't play the media.
