Can you access the load balancer logs? Maybe the load balancer considers your service as unhealthy for some reason? What do you see in the respective application logs? Do you see requests coming in and served in a timely fashion?

which type of load balancer is? Classic, Application or Network ? Internet-facing or private? how about submeta; is it using the same subnets of your instances? (how many instances) ;

you just check if there is any error in the alb long and the check this (https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-troubleshooting.html ) after that I would go through Target Groups and Listeners:ListenerRules and check if there is any problem there too
