Screen Mirroring Problem

[GuneyS]

Hello,

Recently my Mediabox modem was replaced with a Connect Box. And unfortunately the Screen Mirroring doesn't work anymore. I'm trying to connect via iPhone, MAC or iPad, but my LG Smart TV doesn't show up in the Screen Mirroring list anymore. All of these devices was connecting to my TV without any problems before I replace my modem with Connect Box.

The TV and the Apple devices are connected to the same network.

Also, if I open the Youtube app from my Apple devices, I can connect to TV's Youtube app with no problem.

I believe a setting of the Connect Box restricts my devices to connect to TV. Could anyone help me on this?

Thanks in advance.

The problem is solved. It was a problem related to TV. Paired devices needed to be reset.
