When changing a registry to serve over TLS, in the deploymentconfig, change the livenessProbe and readinessProbe scheme from HTTP to HTTPS:

        livenessProbe:
          httpGet:
            path: /healthz
            port: 5000
            scheme: HTTPS
            ...
        readinessProbe:
          httpGet:
            path: /healthz
            port: 5000
            scheme: HTTPS
            ...
