Apple TV 4 not working with Homesharing

Can you ping your ATV4 from your iMac?

Do you have a firewall active on your iMac?

Did you try if you can connect using an ethernet cable?

Did you try connecting your ATV4 directly to your iMac via cable, to make sure no other component is interfering?

Hi

Have you go home sharing on all your apple devices including Atv 4.

Cheers

You were able to ping your ATV. That's good. But an answer time of over 115 ms is way too long for a local network. 1 or 2 ms would be ok, but 115 ms indicate that something isn't well configured on your network. My answer times pinging servers on the other side of the world are shorter than that.

To make sure your iMac and your ATV are working properly together I'd connect them directly to each other, with no networking device in between. But then you'd have to configure both network cards (the one in your iMac and the one in your ATV) manually, as you won't be able to obtain automatically assigned IP addresses, if that's how your network is configured.

If the above procedure doesn't work, then either your iMac or your ATV is broken or miss-configured (assuming that the ethernet cable is OK).

If the above procedure does work, then your network is miss-configured.

Did I get that right? Your ATV4 and your iMac were able to talk to each other via Home Sharing until last Thursday? That information is new.

How did you reset your ATV4? Did you reboot it via user interface? Did you restart it by unplugging the power cord? Or was it a factory reset?

What did you change in your setup on Thursday/Friday, at around the time it stopped working?

Do you have more than one AppleID?

Are you using the same AppleID for both devices, iMac and ATV4?

You have two iMacs. Do both of them have an iTunes library that you're sharing on your network?

Are you connecting to the right library?

Did you try shutting down all other components in your setup, leaving only your main iMac, your ATV4 and your wifi device active?

Is there anybody else in your household who might have changed something in your setup?

Are there other wifi networks nearby? A neighbor might have changed his/her setup, which might be interfering with your's now.

There is so many variables. I could go on and on with my questions until ATV5 comes out and beyond. It's pretty pointless, until you make sure your ATV4 isn't actually broken. The easiest way would be the use of an ethernet cable. Another way would be to bring your ATV4 to an Apple Store or an authorized Apple Service Provider and have them check it. Not sure if it would cost you money.

I Had the same problem I paid for iTunes music match instead

I'm glad to hear you found the error.

Just to clarify for anybody reading this:

What you find in iTunes -> Preferences -> Sharing has absolutely nothing to do with Home Sharing. It's a means of sharing your iTunes library in XML format for other apps on other computers on your local network, like for movie or music editing apps.

Only via iTunes -> File -> Home Sharing you can actually enable/disable Home Sharing.

Thank you! I came here to find this very answer. I've had this problem for several weeks and it was driving me batty.
