Traffic Jam

The pods work. The Service exists. The Ingress is configured. Yet: 503. Something invisible is blocking the traffic.

20 min
Initial Situation

A microservice was deployed behind an Ingress controller for external access. The pods are Running and respond perfectly when accessed directly. The Service configuration looks correct and matches the pod labels. But accessing through the Ingress consistently returns 503 Service Unavailable.
