@tolik93, do you have other integrations like Istio? Is your cluster getting connected to the Cloud? In a case with similar error message, the Ambassador Agent was unable to communicate with Edge Stack. The fix was to turn off the Istio sidecar for non-essentials in the Ambassador namespace to stop the Istio sidecar from interfering with the Ambassador Agent.

@cindymullins-dw Thank you for your answer. Yes, I use Istio Integration and it automatically injects a sidecar Istio Proxy to all pods. It would be great, if there were a Helm Chart value option, to annotate agent pod. In my case, I have to annotate agent pod manually with sidecar.istio.io/inject: 'false'
