Hello.
Do the inbound rules of the EC2 security group allow HTTP port 80 and HTTPS port 443?
Also check the inbound and outbound rules in the subnet's network ACL.

Yes, it’s all done, still am facing the problem
Probably Tomcat's listening port is 8080, so even if port 80 is allowed in the security group, it cannot be accessed. If you change Tomcat's listening port to something like 80, you can connect by allowing port 80 in the security group. Of course, if you want to continue using port 8080, just allow port 8080 in your security group.
