My mistake, let me correct my comment.
On
*wireless network side, all you need to do is to make sure directed multicast is disable on WLAN interface and eth interface and client isolation is turned off.
To disable directed multicast, I have already shared the 1st link in previous comment.
If still it is not working, I will suggest to open a case with support to troubleshoot further.
