Plex Binding - Samsung Smart TV

He guys,

running into some problems with the plex binding.
It is working for plex on my phone.
But when i try to use buttons on the plex samsung smart tv app Openhab gives this error:

2020-09-07 17:55:13.174 [ERROR] [.binding.plex.internal.PlexConnector] - Error sending command to Plex

java.io.IOException: Remotely Closed

2020-09-07 17:55:15.180 [ERROR] [.binding.plex.internal.PlexConnector] - Error sending command to Plex

java.io.IOException: Remotely Closed

It is able to get info from the tv but when i use control buttons it gives the error:


This are the settings in Paper UI.

Read a post that said to add the direct url to raspberry host:

Did not work. I think it has something to do with the TV cause on my phone its working fine.
Someone has an idea to get around this?
