IBM Cloud Private 3.1 - unable to login to URL: Unexpected response code 401 from request - kubernetes

Question

I have successfully installed IBM Cloud Private 3.1.
All was working well. I could login to the ICP URL, but after rebooting, nothing works.
Now the URL says:
Unexpected response code 401 from request: GET
https://icp-management-ingress:8443/idmgmt/identity/api/v1/users/admin/getTeamResources?resourceType=namespace
HTTP/1.1 Accept: application/json Authorization: bearer *** HTTP/1.1

X-Content-Type-Options: nosniff X-Dns-Prefetch-Control: off
{"error":{"statusCode":401,"name":"Error","message":"An error occurred
while accessing the kube services rest api"}}
When I try to login with cloudctl, I get this:
Cloudctl login
API endpoint: https://172.31.16.153:8443
Username> admin
Password>
Authenticating...
OK
Select an account:
1. Mycluster Account (id-mycluster-account)
Enter a number> 1
Targeted account mycluster Account (id-mycluster-account)
FAILED
Error response from server. Status code: 401; message: {"error":{"statusCode":401,"name":"Error","message":"An error occurred while accessing the kube services rest api"}}
And kubectl says there is no service for the common ones:
Kubectl get pods
Error: The server doesn't have a resource type "pods"
Kubectl get nodes
Error: The server doesn't have a resource type "nodes"
Kubectl get services
Error: The server doesn't have a resource type "services"
Kubectl get deployment
Error: The server doesn't have a resource type "deployment"
Any suggestions?
