Whatsapp call on IOS latest not working

Hello
I'm facing a critical problem with the firebox. all WhatsApp calls users on iPhones 13 and 14 are not working. whilst on android devices, everything is working fine.
is there any hint to fix that?

    If you turn logging up for your proxy in that proxy action's settings (under general) you may see more information. Based on what I can see here the proxy is timing out trying to contact the servers at 20.199.120.15, 84.17.42.172, and 157.240.203.34.

    -Does the connection work if you send it through a packet filter? (This is the fastest way to determine if the proxy is potentially causing the problem vs just reporting back info to you.)

    -Do the android clients use a different IP to connect?

    -Do the clients display any kind of error message? (Bad certificate, bad TLS connection, etc?)
