There are some probable reasons for these notifications.
The first possibility is that the location lacks an operational internet network. It’s possible that the service provider, router, or cable is not the cause of this.
The television’s internet connection may also not be set up correctly on the device, which is another option. This might be due to incorrect internet being picked up or the internet settings are not properly configured.
Finally, it is also possible that a virus or other malicious software has taken control of the TV and is blocking internet access.
