Hi Team,

I have setup rancher on my eks cluster. When I try to import other clusters from rancher portal I am getting error:

Failed to communicate with cluster: Unauthorized

I am able to create the cluster but not able to import the clusters.

Can u please let me know why it is happening?

Rancher Version : 2.6.0

Also having this issue, no problem when I was on 2.5 with the same process

Steps: Set up amazon IAM user Configured cloud credentials imported eks cluster in "Failed to communicate with cluster: Unauthorized"

Try to update the configmap file of the cluster which you are importing to the rancher. Run the below command:

kubectl edit configmap aws-auth -n kube-system

Add below configuration to your configmap file (below mapRoles) and save it:

**mapUsers: |

groups:
- system:masters userarn: <AWS Credential IAM User Arn> username: <IAM User Name>**

And then try to import the cluster.
