I have react app built with webpack, running on port 3000.

Task Definition set up using AWS Fargate, with soft/hard memory of 256 and CPU units 256. ECS launch type also using AWS Fargate, with inbound rules security group using TCP port range 3000 as well. Currently not using any load balancer.

When I check using public ip address : 3.222.200.55 or 3.222.200.55:3000, both doesn't work

Help please.
