I am installing service catalog which uses CRD and have created the same. Now I am running my controller deployment file and the image running in it runs a CRD list command to verify CRD are in place. This use to work fine previously but now CRD Probe is failing with error:

1226 07:45:01.539118       1 round_trippers.go:438] GET https://169.72.128.1:443/apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions?labelSelector=svcat%3Dtrue  in 30000 milliseconds

Error: while waiting for ready Service Catalog CRDs: failed to list CustomResourceDefinition: Get https://169.72.128.1:443/apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions?labelSelector=svcat%3Dtrue: dial tcp 169.72.128.1:443: i/o timeout

I have followed same steps as previously but could not debug now.

Inside the controller code it is trying to make following call:

list, err := r.client.ApiextensionsV1beta1().CustomResourceDefinitions().List(v1.ListOptions{LabelSelector: labels.SelectorFromSet(labels.Set{"svcat": "true"}).String()})

Which is failing.

Update 1 : Installation works fine in default namespace but fails in specific namespace.
