Dask + Fargate tcp connection timing out

Hello, I am trying to deploy Dask cluster on Fargate. I managed to deploy the cluster and also can see the Dask status screen via the public http address, but not able to connect using the tcp channel.

I have used this article as reference "https://gist.github.com/jacobtomlinson/ee5ba79228e42bcc9975faf0179c3d1a" and tried several combinations of Inboud/Outbound rules on the security group.

I used sage make to create the cluster. Any help will be very much appreciated.

Best
