The installer could not verify that Ambassador Edge Stack (AES) is answering queries. This can happen if AES took longer than expected to start up, or if the load balancer in front of AES is not reachable from this computer (your developer machine).
- Verify that the load balancer address is reachable from this host
- Run the installer again:edgectl install
Don't worry: it is safe to run the installer repeatedly on a Kubernetes cluster.
