Update the TCP idle timeout for your Gateway Load Balancer listener

For each TCP request made through a Gateway Load Balancer, the state of that connection is tracked. If no data is sent through the connection by either the client or target for longer than the idle timeout, the connection is closed. The default idle timeout value for TCP flows is 350 seconds, but can be updated to any value between 60-6000 seconds.
