ghp serves metrics over HTTPS (TLS configured globally), but the liveness/readiness probes used the default HTTP scheme, so the kubelet probe hit an HTTPS-server error and pods never went Ready. Set scheme: HTTPS on both probes (kubelet does not verify the probe cert). The VMServiceScrape targets that same HTTPS endpoint, so set scheme: https with tlsConfig.insecureSkipVerify (internal-CA cert, pod-IP target not in the cert SANs); otherwise VM scraping of ghp fails. - deployment.yaml: liveness+readiness probes scheme HTTP -> HTTPS - vmservicescrape.yaml: scheme https + tlsConfig.insecureSkipVerify
