Constant Backend Connection Errors in AWS Load Balancer

I am trying to use a load balancer with AWS ECS on AWS. For some reason, the graph always looks like

enter image description here

This happens even when there is no request coming to the load balancer at all. I cannot find this in logs either. What do this mean and what cause it?

I faced a similar issue some time back. It is most likely caused by the health checks you have configured on the ELB. Try changing the health check to port 22 and see if it goes away. In my case, opening up the health check port in the EC2 security groups fixed it. Hope this works for you.
