I do not have my Plex server running on a Mac OS (Windows 10 system), but I’ve run into the problem where Apple TV could not connect or could not find any Plex server on my network. It suggests that I check firewall and make sure that my Plex server is up and running.
My resolution was:
- Removing “Devices” from the Plex server (Settings-> Server-> Devices). I had previously created and used two older Plex server names (migrated folder directory location, changed hard drives, etc) that were never removed from this list. I deleted the two names and left only the latest Plex server name on the list.
- From the Apple TV, I went ahead and deleted the Plex server app completely. Just press and hold down on the Plex server app with the remote touchpad then press the >|| button to confirm and delete.
- Go to the App Store and search for Plex, download it from the cloud.
- Link the app to your account again.
Finally it showed my existing Plex server name on the network. I just selected it and immediately had access to all synchronized media again. Hope this helps.
