An error occurred while connecting to the AirPlay device “Apple TV”. An unknown error occurred (-15000).

Hi ,

I acquired an Apple TV (Gen3) a couple of days ago.

The Apple TV seems to be connected properly to WIFI (Good signal)

I watched streaming videos on Youtube and film trailers – the speed is ok.

I followed the protocol but, still, I cannot connect Itunes to the Apple tv.

These are the error messages:

On the TV : apple tv could not connect to library

In Itunes: An error occurred while connecting to the AirPlay device “Apple TV”. An unknown error occurred (-15000).

Please note that Apple TV doesn’t appear in the list of devices in Itune’s preferences menu.

The Home Share is enabled on both devices and I connected with the Same Apple ID on each device.

Airplay is on.

Ref Apple TV :

Apple tv: Model MD199HC/A

Serial number DY******RHN

apple tv software : 5.3(6105)

Imac: OS X version 10.8.4

I already tried to :

Unplug/plug modem and router

Test connectivity

Disable the Firewall

Re-enable the firewall with Itunes in the list of ‘allowed’ devices

Re-set Apple TV (3 times) + Up to date

Re-start Apple TV and computer several time

Itunes is up to date

Could you please help?

Many Thanks

Sylvie
