Hello, I have an issue connecting 2 machines to elasticsearch. I have 2 redundant machines in azure which have the same software installed, both have metricbeat and filebeat installed which works just fine. Lets call them machine A and machine B. The problem is that in the stack monitoring i see only one of those, for example machine A and sometimes after refresh I see only machine B. Both machines have the same metricbeat and filebeat configuration and work just fine but when only one is active. When beats on both machines are active I see beats from only one machine in the stack monitoring. Beats on those machines have the same exact configuration. Both use certificate to connect to elastic. What should i check? What might be the issue here? ---
