Metricbeat fail with the error: failed to process cluster event (put-lifecycle-metricbeat-7.2.0) within 30s

I am getting the following error, and after a few hours of reasearch and configuration changes I could not find a solution.

Jul 26 00:31:05 am01 metricbeat: {"level":"error","timestamp":"2019-07-26T00:31:05.712Z","caller":"pipeline/output.go:100","message":"Failed to connect to backoff(elasticsearch(https://elasticsearch-url:elasticsearchport)): Connection marked as failed because the onConnect callback failed: 503 Service Unavailable: {"error":{"root_cause":[{"type":"process_cluster_event_timeout_exception","reason":"failed to process cluster event (put-lifecycle-metricbeat-7.2.0) within 30s"}],"type":"process_cluster_event_timeout_exception","reason":"failed to process cluster event (put-lifecycle-metricbeat-7.2.0) within 30s"},"status":503}"}

the error suggest that the metricbeat cannot connect to elasticsearch/kibana, but if I try from the same host a wget to that url I get the following response:

"name" : "elasticsearch-server-hostname",
"cluster_name" : "logging-prod",

"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"

What could be the problem?

Thank you
