I've created a Network Load Balancer for use with ECS Fargate. When I try to connect to the load balancer (using either the ELB domain name or it's IP addresses) it won't connect. I don't even see the connection in the flow logs. The machine I'm using to connect to the LB can reach the instances fine, but when I try to hit it through the load balancer I don't get a TCP connection. The security group on the Fargate containers allows anything from anywhere. The load balancer shows the instances health checks as "Healthy" but I still can't get to them.
