I deploy a application in AWS on e2 instance on
I create a network loadbalancer (application use a tcp protocol) with target group.
Also this instance is in autoscalling group with a proper security group:
- inbound: APP_PORT
- oubound: 1 - 65534
From other ec2 instance I can reach application via LOAD BALANCER DNS name, and is responding also all health check are passing. But on ec2 instance where this instance exist:
- I can reach application via localhost/ec2 ip
- But I couldn't do this via Load balancer dns, I got a timeout
AWS ALB doesn't allow a traffic loop on load balancer or I had something wrong? Maybe I'm missing something...
