Exposing Internal Kubernetes Agent UIs: Lessons from VPC Lattice, DNS, and Private Access

A Kubernetes UI can be healthy but unreachable due to private networking issues. To resolve this, debug in a specific order, starting with DNS resolution and local route table. Check if the hostname resolves to a private IP that your laptop may not be able to route. Compare with a working internal UI to identify the issue. Route53 should point to a VPC endpoint association DNS name for human browser access.
