The issue contains only an inline Kubernetes manifest for a PostgreSQL Deployment and NodePort Service; no repository file or test is named. Start by reviewing the Service and external-access setup, then reproduce the timeout with the stated Minikube host and port. Done would require a confirmed cause and a documented, verifiable way to connect from pgAdmin4.
