Public-health publishes an Ingress that returns edge errors for a citizen API. Investigation shows the Ingress backend Service name does not exist in the namespace. What is the correct diagnosis?
Select an answer to reveal the explanation.
Short Explanation
The Ingress is a map to a suite number that is not on the directory. If the backend Service name is wrong or missing, the edge has nowhere sensible to send the request—fix the Service name and port.
Full Explanation
Ingress backend references must resolve to real Services and correct ports in scope. A typo or deleted Service leaves the controller unable to route to healthy endpoints, often surfacing as edge failures. Controllers do not invent Services from host fields or silently remap misspellings to default/kubernetes.
