ERROR: Apple TV causes AES-CCMP TSC replays

Hello,
I have a problem. I have a Cisco 2702i AP with two wifis. The two networks run on 2.4GHz and 5GHz and so far work without problems.

But as soon as I connect my Apple TV to the wifi, it triggers the following error message and then loses connection for a few seconds. The Apple TV is on the latest software version. In another network (no Cisco AP) it works without problem.

%DOT11-4-CCMP_REPLAY: Client acbc.4586.e8c8 had 1 AES-CCMP TSC replays
%DOT11-4-MAXRETRIES: Packet to client acbc.4586.e8c8 reached max retries, removing the client
%DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station acbc.4586.e8c8 Reason: Previous authentication no longer valid

I have also uploaded my current config of the AP.

Would be very grateful for any help.

Alex

So as @marce1000 has highlighted this appears to be a known bug.
But Cisco will not be fixing it because the product is already way past the end of software maintenance date:
https://www.cisco.com/c/en/us/products/collateral/wireless/aironet-2700-series-access-point/eos-eol-notice-c51-740711.html

You don't mention what version of software you're using now so the only thing I can suggest is to try different versions.
for example https://bst.cisco.com/bugsearch/bug/CSCup72165 is fixed in 15.3(3)JPJ6 and 15.3(3)JK5 - try those.
https://bst.cisco.com/bugsearch/bug/CSCuq91056 possibly (bug details are sketchy) fixed in 8.0.120.0 so try 15.3(3)JA4.

If none of those solve the problem then really nothing you can do other than replace with a currently supported product.
