jaeger collector on AWS ECS

[HaroonSaid]

We installed jaeger collector on AWS ECS - we are seeing the following message

{"date":1647124697.53747,"container_name":"/ecs-jaegercollector-tools_us_dev1-23-jaegercollector-dev1-82b7ebd4f99fb8866b00","source":"stdout","log":"{\"level\":\"info\",\"ts\":1647124697.5371158,\"caller\":\"grpclog/component.go:71\",\"msg\":\"[transport]transport: loopyWriter.run returning. connection error: desc = \\\"transport is closing\\\"\",\"system\":\"grpc\",\"grpc_log\":true}\r","container_id":"7ab578cafb0859d09b0e0e96d7fcea00c1336d91d9fc5856528f4aa213b509a7","ec2_instance_id":"i-0a6e15b76f6e8ff43","ecs_cluster":"tools_us_dev1","ecs_task_arn":"arn:aws:ecs:us-west-2::task/tools_us_dev1/4f9ec8882b5a48108e797eed69280ecd","ecs_task_definition":"jaegercollector-tools_us_dev1:23"}

Any idea what it means?

The configuration is

We have ALB with a private CA port 14250 going to target group to port 14250
