Cases when AWS ELB (Amazon Elastic Load Balancer) does not work

1. Insufficient Capacity: AWS ELB may not work if there is not enough capacity available to handle the incoming traffic. In such cases, the ELB may become overwhelmed and fail to distribute the load effectively.
2. Unhealthy Instances: If the instances registered with the ELB are unhealthy, the ELB may not be able to route traffic to them. Unhealthy instances could be due to various reasons such as network failures, high CPU utilization, or application-level issues.
3. Incorrect Configuration: Misconfiguration of the ELB can lead to it not functioning correctly. For example, if the ELB is not properly configured to listen on the correct ports or protocols, it may not be able to route traffic to the instances.
4. Security Group Restrictions: If the security groups associated with the instances do not allow incoming traffic from the ELB, the ELB will not be able to forward requests to the instances. This can happen if the security group rules are incorrectly configured or if there are network ACLs blocking the traffic.
5. SSL/TLS Certificate Issues: When using SSL/TLS termination on the ELB, if the certificate is expired, invalid, or not properly configured, the ELB may not be able to establish secure connections with the clients.
6. Network Connectivity Problems: If there are network connectivity issues between the ELB and the instances, such as firewall rules blocking communication or instances being in a different VPC/subnet, the ELB may not be able to route traffic to the instances.
