Hey,

Facing the same issue here. But I know Why.

Try to look up there : https://github.com/cilium/cilium-cli/blob/dcfb77269f4887d4f6aebbf19bf58e8ea3b737d1/clustermesh/clustermesh.go#L882

You will probably find a reason why cilium can't auto detect the IP.

In My case I am on a on premise cluster so LoadBalancer does not assign an ip. And since it is based on status field I can't use that...

Hope this helps

I faced this when I did an AKS-to-AKS setup. I realized --service-type LoadBalancer was PENDING however I just got done setting up peering between vNets, and I should be able to use ClusterIPs between the peered networks.

# enable cilium cluster mesh
# use ClusterIP since we have peering between the clusters
cilium clustermesh enable --context $AKS_USA01_NAME --service-type ClusterIP
cilium clustermesh enable --context $AKS_DEU01_NAME --service-type ClusterIP
cilium clustermesh enable --context $AKS_JPN01_NAME --service-type ClusterIP

# Finally, connect the clusters. This step only needs to be done in one direction. The connection will automatically be established in both directions:
cilium clustermesh connect --context $AKS_USA01_NAME --destination-context $AKS_DEU01_NAME
cilium clustermesh connect --context $AKS_USA01_NAME --destination-context $AKS_JPN01_NAME
