How to Troubleshoot Kubernetes Ingress That Returns a 404 for One Service

A route-specific 404 may come from host or path matching, ingress class, service port, or application routing.

Checks to make

Compare ingress rules with service selectors and port names, inspect controller events and access logs, and test the service directly from within the cluster. Check exact hostname and path rewrite behavior before changing controller defaults.

When to get help

Kubernetes operations can trace ingress routing from edge to service. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
