I have a solution (AnzoGraph DB) deployed on my AWS Kubernetes Cluster (EC2 Instance), and was working totally fine. Suddenly this solution stopped and i could not access it via the DNS anymore. I tested the solution deployed on my cluster using kubectl port-forward command and they are working fine (the pods and services), thus i assume the problem is with AWS Loadbalancer.
To access the application we need to go through this path: Request -> DNS -> AWS Load Balancer -> Services -> Pods.
The LoadBalancer is (classic) internal, so it's only accessible for me or the company using VPN. Every time when I try to access the DNS , I got no response.
Any idea how i can fix it ? or where is the exact issue ? how can I troubleshoot this issue and follow the traffic on AWS ?
Thanks a lot for the help!
