Hello,
I have a Plex server set up on a windows PC and i use a Samsung tv as player.
Everything works correctly when both the PC (Server) and TV are connected to the wireless network, but when i connect the PC through Ethernet (coming from the same router), i can still connect to the library on TV but the movies don’t play anymore. I just get a black screen.
Any idea how could i fix this? As i would prefer to keep the server connected via Ethernet.
Thank you.
I actually have seen this Issue on my Samsung that I just bought for a spare room.
No issues with the native app on my LG in another room.
Do you have other Plex clients - phone, PC, other TV?
Can they connect & play media OK when the server is using Ethernet?
Please try these steps:
Disable WiFi on the Plex server. You want it to stay disabled after a reboot.
Make sure the Ethernet port on the PC is configured as a Private network in Windows (Win 10: Settings → Network & Internet → Status).
In Plex Settings → Network, select the Ethernet port as the preferred network interface.
Reboot the server.
When server & Plex are back online, try to play media from various clients.
Hello,
Thank you for your answer. I followed the steps you provided but to no success.
I tried connecting from other devices Phone/Laptop which where bot connected to the wireless network and the video plays fine. Only the TV seems to be having this issue.
On the other devices i got the message:
“You are not connected directly to this server so streaming quality may be limited. You may be able to connect directly to this server by changing your home network settings. Learn more”
Don’t know if it has anything to do with it or not.
Thank you.
This means the client is connecting via Plex Relay. The connection is tunneled through a server at Plex and limited to 1 Mbps (2 Mbps w/ a Plex Pass).
You may be running into a DNS Rebinding situation.
If possible, configure your Plex Server to use a public DNS server such as:
The reboot the server (or flush the DNS cache if you do not want to reboot).
See the DNS Rebinding section of How to Use Secure Server Connections for additional information.
Note: As you might have noticed, Plex is getting crushed today with password reset requests. This is affecting operations of many of their services, including authentication.
You may see errors/timeouts when your server or host tries to communicate with plex.tv hosts. If this happens, wait a bit and try again. Hopefully the traffic level will subside later today.
I tried setting the DNS server directly in the router but still not working.
What i noticed though is that the server is transcoding the file, even if the TV can play it natively.
I also tried with a low resolution file and it still tries to transcode.
The problem is the Indirect connection. This tunnels your connection through a server at Plex and is limited to 1 Mbps. That is why things are transcoding.
Something is wrong with your local network. The connection in Plex Dashboard should say “Local.”
Changing DNS should help with DNS rebinding issues.
Other devices can stream from wireless, so server config and network appear OK.
I’m running out of ideas… 
One more thing to try.
Note: Plex systems have been under heavy load due to all the password resets. This includes the authentication servers, which are used by the Plex app on your TV when you login.
If you are unable to login to your Plex account in the TV app, it is probably due to the load on the server. Wait and try again in a few hours. Hopefully the load on Plex’s systems will be less.
Uninstall the Plex app from the TV.
Power off the TV.
Remove the power from the TV (unplug it from the mains) and wait 1 - 2 minutes.
Restore power and power on the TV.
Re-install the Plex app.
Launch the app, login, and see if you can stream anything. The app will have default settings, so change whatever settings you need to match your setup.
Thank you for the effort :).
I also contacted my ISP, maybe they can help with solving this issue.
