I am using linkerd and have two clusters (west and east) in GKE, each of them has 3 nodes. I exactly followed the steps in official documents for multicluster. when I try to run check on west I get the following error:

linkerd --context=west multicluster check

I searched over web and also see this related thread but still can’t find the issue. How can I resolve this issue

NOTE: The thread I mentioned tested on local not on any cloud provider. but my problem appears on GKE. I don’t use kind or any similar local tools.
