Unable to connect with kubectl to a GKE cluster

Question

I am currently trying to connect with kubeclt to a GKE cluster.

I followed the steps in the documentation and executed successfully the following:

gcloud container clusters get-credentials <cluster_name> --zone <zone>

Some days ago it work perfectly fine. I was able to setup a connection with kubectl. The configuration was not changed in any way. And also still try to accessing the cluster through the same network. The cluster itself is running stable. Whatever I try I run into a timeout.

I have already had a look into the kubectl configuration:

kubectl config view 

It seems to be that the access token is expired.

...
expiry: "2022-08-01T12:12:35Z"
expiry-key: '{.credential.token_expiry}'
token-key: '{.credential.access_token}'
...

Is there any change to update the token? I am not able to update the token with the get-credential command. Already delete the configuration completely and run the command afterwards. But the token is still the same.

I am very thankful for any hints or ideas on this.

Have you tried rerunning your credentials command again to refresh your local kubeconfig?

gcloud container clusters get-credentials <cluster_name> --zone <zone>

Alternatively, try the beta variant:

gcloud beta container clusters get-credentials <cluster_name> --zone <zone>

(You may need to install the beta package using gcloud components install beta )
