Apple TV not responding-Port 3689

AZWally, as a fellow user in the same boat, I am sorry you're having this problem as well.

Take a look at the similarly titled thread in this discussion area and you will see that many have had or are still experiencing the same problem. Some have resolved theirs and some have not.

After working with them all day today, Apple was unable to correct this issue on my machine and is really puzzled as to what may be wrong. They're working on the problem, however, and are supposed to get back with me tomorrow afternoon. I'll certainly keep both these threads updated as to any resolution or lack thereof.

You're welcome and not your fault on the thread thing....the original thread was on page 2 before I added my 2 cents.

*Once you have synced or paired the Apple TV to your Mac to establish a syncing or streaming connection, iTunes may say "The Apple TV [Name] is not responding. Check that any firewall software running on this computer has been set to allow communication on port 3689."*

Is that the message you get, or are you saying you have re-linked the library (pass code) as a troubleshooting step and then get the message: "The Apple TV [Name] is not responding. Check that any firewall software running on this computer has been set to allow communication on port 3689."

I'd like to add my AppleTV to this thread as well. It has started to produce the 3689 error since upgrading to Snow Leopard / iTunes 9. Exactly the same situation: firewall not enabled at all.

I actually did a total wipe and resync the other day (which worked), but it just stopped syncing again after a day or two.

It did work without problems for at least a year, so I do suspect something in SL or iTunes 9 is causing it.

By the way, could it possibly have something to do with the new Wake on Demand and Bonjour Proxy services? Does the ATV actually know about Bonjour Proxies yet?

AZWally, wish I had better news for you. I had a phone appointment with a top tier Apple tech today at 2:30 but he never called. Very un-Apple like behavior, I must say. So, anyway, my problem is still unresolved. Any progress on yours? Looks like quite a few people have been experiencing this problem.

I figured out what was causing my problem. I have two IP-adresses. One on my local network and one the end-point of a tunnel (to the office). For some reason, iTunes starts talking to the AppleTV from the tunnel address at some point(which is a completely different range from the local network), which is when sync stops. The AppleTV still shows in iTunes as packets sent from the AppleTV are still received (local network interface is fine, after all). I'm not sure why it is sending local packets with the wrong source IP-adress, but if I remove the tunnel, sync starts right away.

AZWALLY, Apple got back with me yesterday afternoon but only to say they had heard nothing from "engineering". Hopefully, we will have a fix soon. I'll keep you updated on my progress.

Same here. Removing the second IP-address fixed it for a while, but it has come back. I even "lost" the AppleTV during sync this time.

It has to be iTunes 9 / SL related then, as that's the only thing that has changed recently on this Mac (I did have the IP tunnel before and it never caused problems).
