It appears that you are using a private cluster (The Private Cluster option is enabled while creating the AKS cluster).

Kubectl is a kubernetes control client. It is an external connectivity provider to connect with kubernetes cluster. We can't connect with the private cluster externally.

However, we can't disable this option after the cluster creation. We need to delete the cluster and create a new one with the option "Private Cluster" disabled.

Alternately, you can set up another self-hosted agent which will be in the same Vnet as the cluster and have access to AKS and the Azure Pipelines.

See Options for connecting to the private cluster

The API server endpoint has no public IP address. To manage the API server, you'll need to use a VM that has access to the AKS cluster's Azure Virtual Network (VNet). There are several options for establishing network connectivity to the private cluster.

Create a VM in the same Azure Virtual Network (VNet) as the AKS cluster.

Use a VM in a separate network and set up Virtual network peering. See the section below for more information on this option.

Use an Express Route or VPN connection.

Use the AKS command invoke feature.

Use a private endpoint connection.

Creating a VM in the same VNET as the AKS cluster is the easiest option. Express Route and VPNs add costs and require additional networking complexity. Virtual network peering requires you to plan your network CIDR ranges to ensure there are no overlapping ranges.
