Ping no work for my jitsi

Something I no understand, please explain me. I make new jitsi for aws, he work fine. I do 2, 3 people call he work fine. But I ping aws ip and even my jitsi url he no respond. But my jitsi are work. What is this?

If you didn’t allow ICMP packets on AWS firewall, this is normal
