the fabric8 failed to access resources /k8s/api/v1/proxy/...

[ica10888]

I have installed fabric8 by helm ,but I can't use it.
When I try to create application , the server shows Not Found.
The console:
POST http://192.168.80.128:21905/k8s/api/v1/proxy/namespaces/default/services/jenkinshift:80/oapi/v1/namespaces/default/buildconfigs 404 (Not Found)

{
"kind": "Status",
"apiVersion": "v1",
"metadata": {},
"status": "Failure",
"message": "the server could not find the requested resource",
"reason": "NotFound",
"details": {},
"code": 404
}

and also I can't access resources
GET http://192.168.80.128:30975/k8s/api/v1/proxy/namespaces/default/services/jenkinshift:80/oapi/v1/namespaces/default/buildconfigs 404 (Not Found)

What is the reason for it?
